Summary. Hello, dear, happy to serve you, here for you to find out.

If you cannot set the passwordless option of the lock screen password, we recommend that you use the following methods to check the passcode one by one:

1) Caused by the application of security policies.

Since some apps have set security policy permissions, the system must set a lock screen password to use this kind of software, so please check whether you are logged in to the app with a security policy (such as: Exchange account, AnyOffice, mobile phone, etc.), if so, please log out of the account of the above app first, and delete the credentials.

Note: Deleting credentials clears the user's account information at the same time as they are deleted.

2) After the special application is activated, it is not allowed to cause "no password".

Go to Device Manager to apply Temporary Deactivation: Device Manager, Temporary Deactivation.

3) If you still can't solve the problem after trying the above methods, please do it as follows:

a.Pattern password: Enter the set pattern password;

b.Enter the backup digital password to turn off the screen of the phone;

c.Unlock the screen and enter the wrong pattern password 5 times, wait for 1 minute;

d.Enter an alternate passcode and it will be automatically set to no passcode.

Note: When the lock screen style is set to no password, the fingerprint unlock will disappear.

For security reasons, the backup passcode function has been removed from the EMUI platform of some products, so this solution is not applicable.

4) If the problem still can't be solved, please back up your phone data and restore it to factory settings.
