Why do I need to enter a password when Mac key strings frequently pop up?

Solution to frequent pop-up of mac key strings:

1. If you forget your password, you can create a new key string without prompting you to enter the password.

2. If no prompt is displayed for the key string or you do not select to create a new key string, you can simply find the previous password: (use the boot password as the default password when the key string is created for the first time, if the key string password is the same as the power-on password, you do not need to verify the key string password. After changing the power-on password, the current key string password is: the previous power-on password of the computer)

1. Open the key string access --- edit (menu bar) -- change the key string 'logon 'password (the key string access is in Launchpad-other). The current password is the previous login password of the account, enter the new password as the new boot password for this account.

2. After modification, you will be prompted to enter the key string password of the 'local Project' (the password of the local project may not be modified together at this time). You can lock the key string in the upper-left corner, click "unlock". After entering the password for verification, the system will automatically prompt you to change the key string password of the local project (this step is not required if the local project password is modified together ).

3. If you do not receive a prompt about the key string password or choose not to create a new password, and forget the previous password, you can use the following method:

Press and hold the option key and click go to-Resource Library, delete the keychains folder, restart the computer, and select create new key string (if you do not press the option key, the resource library option will not appear)

No resource library is available without pressing the option key.
