Therefore, in the first hand, you should check that your iPhone model supports face ID or not. There are a lot of causes that "Face ID is not working", firstly you need to check your iPhone thoroughly. Which iPhone Models Support Face ID?   Facial ID technology is the latest feature for the iPhone. That's why only some models on the market feature it relatively. Only iPhone XS Max, iPhone XR, iPhone XS, or iPhone X allows this feature, so you can set up as well as using facial ID on your phone if you have one of those models. However, the previous models do not have this feature. Check for the Latest Updates Once you have analyzed that your iPhone is one of the models supporting facial ID, you should check for any updates to iOS. Therefore, make sure to back up your iPhone by using iTunes or iCloud before any updates to be done if you do not want to lose your data. Plug your device into an outlet. Connect to the internet that has high-speed Wi-Fi. Tap to Settings options. Click on "General". If it appears that there is a software update, immediately hit on Install button.  A message will appear which asks you to temporarily remove apps because iOS required additional space for an update.  You are allowed to tap on "Continue" to respond that you want to reinstall the apps later. Check to determine if the facial ID is fixed after you have installed the update. If it has not done its task, then switch to the next option.

The setting can be changed by keeping in mind the steps given as under: Go to Settings Go ahead for Face ID and Passcode. Check it out if Face ID is set up in the correct format.

Now you should check if the True Depth camera is not covered in any way. It is what the iPhone uses for this feature. The True Depth camera is located near the top of the front of your iPhone. If your phone has a screen protector that is blocking the camera, you will have to remove the protector for this feature to work correctly. Furthermore, check for any dirt, grime, or other buildup.  You should check to see if the camera is in landscape mode as well. If it happens, ensure that your palm or finger is not blocking it while trying to use it. If this situation raises continuously, you should look for the alert at the top of the screen, which prompted that "Camera Covered," with the arrow pointing in the True Depth camera direction.

How to Login to Minecraft with Microsoft Account?

We will help secure you and your account by growing account protection and introducing Minecraft's new security features. If you move to a Microsoft account, you can enable authentication of two factors that make access to your account much more difficult for intruders. Over time, we will also improve other player protection features. You must switch to a Microsoft account if you are using a Mojang account to continue playing Java Version. You're no longer going to need it! After migrating, you can log into the Minecraft Launcher using your Microsoft account to play the game. MIGRATE MY MOJANG ACCOUNT TO A MICROSOFT ACCOUNT? We'll let you know when your account is ready to migrate on your profile page on Minecraft and the Minecraft launcher. You can only click on the advertisement to migrate if you are told that you are registered. You won't have to wait a little longer if you cannot locate the announcement on Minecraft.net or the launcher in Minecraft – but we'll let you know when your turn is going to take. Five simple steps are taken in the migration process. To migrate, click the ad. Sign up on an existing Microsoft account or build a new Microsoft account if you have not already. Set up your profile — don't worry, this doesn't need an Xbox. Confirm your Microsoft account migration. Farewell! Now with Microsoft: Java Version, you can play Minecraft. LEGACY MINECRAFT ACCOUNT TO A MICROSOFT ACCOUNT You have time to migrate – when you get the email, you don't need to travel right. However, you will need to transfer your account or risk closing when the voluntary migration period expires. Not at the moment. We will soon have a solution, but you can continue to log in with your legacy Minecraft account in the meantime. In 2010-2012, Legacy Minecraft accounts were used. If you have a user name instead of an email address, you know that you have one. Don't worry; exactly how you log in to the game is the only thing that changes. We switch Mojang accounts to Microsoft accounts only, enabling you to have access to new protection. Minecraft: The Java Version will remain the same, and in the future, we shall keep updating and promoting it. ACCOUNT HAS BEEN COMPROMISED?

Face ID VS Fingerprint: Which Is More Secure?

Our data is the most precious asset for us. We have to keep it safe from cybercriminals. Therefore, we must know about security apps to protect our phone and personal data. Now the question is: Face ID VS Fingerprint; Which is more secure? And which one is to be chosen?  Fingerprints are the security key Rather than most of us rely on two critical elements of our fingerprint data that only we possess and no one else. There are two main options for those who are looking for an app to secure their devices that entirely rely on Face ID. As we know, face ID has its benefits as well as drawbacks, fingerprint also owns many benefits, drawbacks you should know. The Apple iPhone has long had Touch ID. It has a fingerprint sapphire crystal sensor which unlocks the phone only if the pattern matches. This kind of match used not just the whirl of your fingerprint. It also includes the location of your skin's clear pores to ensure that it was you who was trying to access the device. However, Apple removed the home button with the iPhone X, which can open your phone with a fingerprint. Despite it, Apple offered something unique that is Face ID.  The security level of Face ID Apple demanded a sleek front phone and removed the home button that had been the base of the device since its starting. Then it offered an alternative that was more simplistic, but few argue less secure. The owners of the mobile point at camera, face, and unlock their smartphones rather than using a fingerprint. Furthermore, it is designed to be a friction-free process. However, this one is considered less secure. Research has proven that it is possible for strangers who have similar facial features got success in gaining access to your phone. The reason is simple because the technology works on a lower resolution.  Unlike fingerprints, facial features are not at all unique.  Researchers somehow managed to use social media pictures to spoof facial recognition security. It was done even before Face ID was released. This process is more straightforward than creating fake fingerprints. However, face recognition is considered to be better than no protection at all, but it is not relatively more secure than Touch ID. Reliability It is improbable to have as catastrophic consequences as many fears. Most accidental unlockings are likely to happen between family members instead of a criminal managing to obtain access. Therefore, the reality is that facial recognition is less reliable than fingerprints for gaining access to phones and devices.  On the other hand, fingerprints have also proven to be get hacked. The fingerprint is strong enough to protect users from ordinary or opportunistic attackers which is substantially better than nothing. Moreover, if you are after quick and easy access to your phone as well as happy to trade off some security for that, then, in this case, relying on Face ID is a good alternative. However, you have to be just careful while storing vital information on your phone, which anyone could access. Authentic Security System Both Face ID, as well as fingerprint, is secured as declared by Apple. However, for the most part, that is true too. It is sporadic that a random person could unlock your phone. However, that is not the only type of attack to worry about it. While using different biometric authentication methods; Face ID and Touch ID are very similar in functioning.  When you try to log in to your iPhone either by pointing your face at the camera on the front, or you put your finger on the touch sensor, the phone immediately compares the biometric data. It reaches and detects the data that is saved in the Secure Enclave. Furthermore, there is also available a separate processor that's entire purpose is to keep your phone safe and secure. Your iPhone unlocks if the face or fingerprint matches. If not, the message will be prompted to enter your passcode. Nothing Protects You from the Government Agencies Nevertheless, any security app can ever truly protect you from a determined government agency with virtually unlimited resources who want to get access to your phone. Not only can they legally bound you for using Touch ID or Face ID to unlock your phone, but they also have access to tools like the GreyKey. Greeley can crack any iOS device passcode that will make fingerprint and Face ID useless for you. Fingerprint and Face ID are incredibly convenient, and if they are backed up with a strong passcode, then it is secure for daily use by everyone. However, they might not protect you for long if you are the target of a determined hacker or government agency.  Conclusion Both fingerprint and face ID is secure, but the fingerprint is more secure as compare to face ID. Anyone who has the same facial features as you can get access to your phone if you are using FaceID. Fingerprint ID is said to be unique as compare to FaceID.

Frequent Error Users Often Meet When Logging In

Despite how much users try to avoid making an error, it is impossible to eliminate user errors. Here we will discuss frequent errors users often meet when logging in.  For most people, logging into sites or apps is standard and a part of their daily routine.  That's why we all intuitively do internet surfing until something goes wrong and an error occurs from our side. For example, we forget our password, username, or the email address through which we signed up. Wrong Username or password When users face a log-in problem, there is a high chance that they have entered a wrong combination of a username and password. It leads to multiple attempts before a successful login. However, it develops fair enough frustration for users, which resulted in their instant quiet.  Furthermore, the Generic responses such as 'Your email or password doesn't match' usually do not provide meaningful feedback for users. It does not allow them to fix user's problems instantly. On the other hand, users, who are not logged in yet, would read, "One of these two fields is wrong but I shall not tell you which one."  That's why it reduces conversion rates and engagement. However, the user should get help via a login task efficiently and effectively. That's why the response should explain exactly not matching correctly that is the password or the email address. Users have Changed Their Password Users make an error while getting so used to typing in their old password that they have forgotten they changed it. As a result, when they see an error message "Your password is incorrect," they simply believe that they're mistyped the password. What users required, in this case, is a reminder that their password was changed.  Rather than giving users a "Your password is incorrect" error message, they need to know how long ago they changed their password. Therefore, this kind of message should only appear when users type in their old password. Most of the time, users mistyped a password then the system displays a regular 'Wrong password' error message to them. Multiple Log-in Errors Users have multiple sign-in options, for example, sign-in through Facebook, Twitter, or Google+ on a site or app. Users might not remember which service they used to sign up for, or they used one at all. Therefore, they hesitate or fail to log in.   On the other hand, if users choose the wrong provider, rather than signing in to the service, they probably end up signing up unintentionally, thereby creating a new account. A site or app capable of perfectly matching accounts from different services but there is no complete guarantee of whether a social media account belongs to the same person. Therefore, for solving multiple log-in problems, users should keep logged in until they explicitly sign out. The fewer people indeed need to log in, the fewer sign-in problems users will have. On the other hand, a further better solution is that remember users when they return. Quora removes the requirement for you to enter a password while re-logging into the service. All you need to ensure is to enter the website and click on your profile picture or name on the log-in screen. Moreover, these solutions have a downside, as well. Such as these solutions work only for people who return to the website while using the same browser. If users log-in by using a different browser or device, this technique will not be much helpful. Determine a 'Forgot Your Password' Flow Like everyone at least once in their life, forget where they left their wallet or keys, users will be likely to forget their password. Therefore, this kind of situation must be handled better by the login process. Furthermore, Login forms offer a 'Forgot Password' link to reset the password for the user. Do not let this link appear after the user clicks on the password field or has already entered the wrong password. Do not allow users to enter their email address again on a forgot password page if they already entered their email address. Then use the forgotten password feature also. Do not send the current or temporary password through an email.  The correct step to send a reset password link is to send it to the registered email address only. Furthermore, make sure that the reset password email sends as fast as possible because users might get disturbed when they will have to wait to login. The reason is that the forgotten password email takes too long to arrive. If users can't access their email, then the full options in this situation will only depend on your kind of service. It makes sense for you to have a few security questions upfront. Therefore, use them as an access point and make it easy if users forget their password.
