forgotten guest user password

Hello,

If I understand your question correctly, you permitted someone to temporarily use your account and now you are unable to remember your password. Thankfully, there's multiple ways to reset a forgotten password, provided that the following apply:

• FileVault is off, or it is enabled AND one of the following apply:
  • You authorized your Apple ID (iCloud account) to unlock your startup disk.
  • If you didn't authorize your Apple ID to unlock your startup disk, you have the recovery key.
  • You know the password to another user that is authorized to unlock FileVault.
• A firmware password isn't set on your Mac, or you set one AND you know the password. Note that this is different from your login password. More details here: How to set a firmware password on your Mac - Apple Support

Methods for resetting your password can be found in this article (as tygb suggested): Change or reset the password of a macOS user account - Apple Support.

The fastest (and usually the easiest) method for resetting your password is outlined below. Note that if FileVault is on, this method will fail if you didn't authorize your Apple ID to unlock your startup disk. Follow these steps to reset your password:

1. Boot Recovery Mode on your Mac by holding down Command-R while you turn on or restart your Mac. Release the keys when the Apple logo and a progress bar appears. If you set a firmware password on your Mac, enter it to continue.

2. When the Utilities menu appears, click on the Utilities tab in the top menu bar, then click on Terminal.

3. Execute this command: resetpassword

4. The Password Reset Assistant should appear. You will be guided through the process of resetting your user account password.

As a sidenote, if you want to let guests use your Mac, you should enable the guest account. It will give them their own user environment (which will get reset upon logout), and will keep your own account and files relatively safe. If FileVault is on, the guest user gets even better in terms of security as it boots to a Safari-only environment, and your entire startup disk is locked and protected.

Hope this helps!
