Changing your Mac login password on purpose is a two-minute job once you know where Apple hid the button. This is the deliberate rotation flow, the one for when you know your current password and just want a new one, not the panic flow for a password you have forgotten. If that is you, jump to every way to reset a Mac password you cannot remember instead.
What you need before you start
- Your current login password. macOS will not let you set a new one without confirming the old one.
- An admin account (or the admin who set the Mac up). Standard users can change only their own password.
- Two minutes. There is no restart and nothing gets erased.
Change your password in System Settings
On macOS Ventura, Sonoma, and Sequoia:
- Open the Apple menu and choose System Settings.
- Click Users & Groups in the sidebar.
- Click the i (info) button next to your account, then click Change Password.
- Type your old password once, your new password twice, add a hint if you like, and click Change Password.
On older macOS (Monterey and earlier) the path is System Preferences > Users & Groups > Change Password. Same fields, older wrapper.
What updates automatically (and what does not)
Your login password unlocks a lot of things behind the scenes, and most of them keep up on their own:
- Login keychain: when you change the password the normal way (inside your own session), macOS re-keys your login keychain for you. You do not have to touch iCloud Keychain separately.
- FileVault: disk encryption stays on and keeps working. Your new login password is now the one that unlocks the disk at boot.
- Apple ID: unchanged. Your Mac login password and your Apple ID password are two different things.
The one case where the login keychain does not follow along is when an admin resets your password for you rather than you changing your own. That reset breaks the keychain link, and macOS will prompt you to create a new login keychain or update the old one at next login.
Pick a password that actually helps
A longer passphrase beats a short scramble every time. Three or four unrelated words are easy to type, hard to guess, and let the built-in Passwords app remember everything else. Skip anything you reuse on other sites.
If you forgot the old password
The Change Password box is a dead end without the current password. There is no override here by design. Your routes are the Apple ID reset, a FileVault recovery key, the macOS Recovery reset assistant, or a second admin account, all walked through in our full reset guide. If none of those work and the Mac is stuck, that is usually the point where selling it makes more sense than fighting it.
FAQ
Does changing my password erase my files?
No. Changing your own password the normal way keeps every file, app, and setting. Only an erase and reinstall wipes data, and that is a last-resort recovery move, not part of a password change.
Do I have to change my Apple ID password too?
No. They are separate. Changing your Mac login password does nothing to your Apple ID, and vice versa.
Will my apps ask me to sign in again?
Almost never, if you changed the password inside your own session, because the keychain re-keys itself. If an admin reset it for you, some apps may ask you to unlock the keychain once.
How often should I change it?
Only when you have a reason, a shared password, a device you sold, a suspected leak. A strong passphrase you keep is safer than a weak one you rotate monthly.
Buying a used Mac and want a clean start?
Every Mac we sell arrives wiped, signed out of the previous owner, and ready for you to set your own login password on first boot, no leftover accounts, no Activation Lock. Browse the Apple clearance lineup: the M1 MacBook Air starts at $569.99 and the M2 Air at $974.99, both set up fresh for you.
