What should I do if I forget the terminal password and the default terminal configuration password?

As shown in the red box in the picture above, this item must be checked, otherwise you cannot reset the password with Apple ID. (If you don't remember checking it, at least remember that the first time you start up OS X or a new Mac with OS X Lion or later, you'll be taken to the OS X Setup Assistant, which asks you to enter your Apple ID.) Once you've entered your Apple ID, select the "Allow my Apple ID to reset this user's password" option during the "Create Your Account" stage.

Okay, here's how to do it: If you incorrectly enter your account password three times in the sign-in window, you'll see a message that says, "If you forgot your password, you can reset it with your Apple ID." Click the icon with an arrow in the circle to bring up the Reset Password dialog.

Enter your Apple ID and password, then click Reset Password to continue. In the dialog box that appears to notify you of the new keychain information, click OK. Enter a new password, a verification password, and a password hint field, then click Reset Password to continue.

Click Continue to Sign in to finish signing in with the new password you just created. Note: Changing the user account password will create a new keychain.

The previous keychain still exists, and you can access it if you remember your previous password later.

2. Use the OS X installation CD or USB flash drive to reset the user account password. Plug in the USB flash drive or CD, press and hold the option to enter when you boot up, after entering, select the language first, a toolbar will appear at the top of the screen, find the utility on it, find the "reset password" in the utility, select the Mac OS X hard disk volume after entering, and select the username of the original administrator account.

As shown in the figure, after entering the new password, click Save and restart the computer. Note: Do not select System Administrator (root). This account is actually the root user. Don't confuse it with a normal administrator account.

The original Linux system forgot the user's password in the terminal.

In my case, I forgot the switch password when I applied the terminal command su to switch users on the ubuntu system installed in VMware.

Solution: Restart the computer and press and hold the shift key until you enter the grub boot mode, select the second line of Ubuntu advanced options, and press the enter key.

After entering the interface, select (Recovery Mode) and press E to enter (Recovery Mode) to compile the kernel and start the parameters.

When the critical time comes, the penultimate line, you will see a line of linux boot...ro recovery nomodeset, remove recovery nomodeset

Add quiet splash rw init= bin bash after the deletion. Then press F10 to start.

If all is striking, after running the system directly into root mode, type: passwd, the system will prompt you to enter a new password, over. Restart your computer.

Hello, I'll help you solve this problem! What should I do if I forget the default terminal configuration password? The steps are as follows:

It can be retrieved by re-missing celery factory settings. The operation steps are as follows: 1. When the router is powered on, hold the reset hole or button for about 10 seconds, and wait for the indicator lights on the router to turn off and turn on again, and the router will be restored to factory mode successfully.

2. The computer connects the router through the network cable, and uses the default IP address of the router and the default login username and password to log in to enter the router background. Note: After the router is restored to factory settings, you need to reset the Internet parameters to have a normal Internet experience.
