To modify the password on your Mac, you can follow the following steps: 1. Modify the login password: Open the system settings or preferences, enter the user and group, select the current user and click "Change Password...", enter the old password and a new password that meets the complexity requirements; 2. Update the keychain password: If the keychain password is not synchronized after changing the login password, you can open the keychain access, right-click the "login" keychain to select Change password, and set it to the same as the login password; 3. Change the password through the terminal command: Enter the passwd command in the terminal, and enter the current password and the new password as prompted. Note: If the keychain unlock fails after modifying the password, you need to manually update the keychain password or consider resetting the keychain, but the saved password will be lost.

Changing the password is actually not difficult on Mac, but people who operate it for the first time may be a little confused. The point is to find the correct path and follow the prompts to do it step by step. The interfaces of different versions of macOS may vary slightly, but the general process is similar.

The following are several common situations to talk about how to operate.

Modify the login password

This is the most commonly used method of changing passwords, which is suitable for the account password you want to change when you boot or log in.

The steps are as follows:

• Turn on System Settings or System Preferences
• Enter Users & Groups
• Select the current user and click "Change password..."
• Enter the old password, new password and confirm

Note: The new password must meet the complexity requirements, such as the combination of upper and lower case letters, numbers and symbols. If the Apple ID login keychain is set, after changing the login password, the system may prompt you to update the keychain password.

Use Keychain Access to modify the keychain password

The Mac's keychain saves passwords for various websites, WiFi and apps. If you change your login password but don't automatically synchronize the keychain password, it may affect the normal use of some functions.

You can adjust manually:

• Open the application → Utility → Keychain access
• Select "login" keychain on the left
• Right-click to select Change Password
• Enter the old password and set a new password that is consistent with the login password

If this step is not processed, sometimes a prompt of "keychain unlocking failed" will appear. In this case, you can also consider resetting the keychain, but it will cause the previously saved password to be lost.

Change password through terminal command

If you are familiar with the terminal or want to operate quickly, you can use this method.

Open Terminal and enter:

 passwd

After entering the car, you will be asked to enter the current password and then enter the new password twice.

This method is suitable for experienced users. Ordinary users recommend that you use the graphical interface more intuitively.

Basically these are the methods. Changing the password itself is not complicated, but some details are easy to ignore, such as the problem of the keychain being out of sync. Remember to take a look more when you encounter a prompt and don’t skip it directly.
