Updating Mac Keychain After a Password Change

Written by Corey Shields | Jan 13, 2026 3:45:00 PM

If you changed your Mac password and are now seeing repeated keychain prompts, your login password and keychain password are out of sync. This guide walks through how to update or reset your login keychain on macOS Ventura, Sonoma, and Sequoia.

Why Your Mac Is Asking for a Keychain Password After You Changed It

When your Mac password changes without properly updating the login keychain, macOS cannot unlock stored credentials automatically.

This usually happens when:

  • Your password was reset by IT
  • You changed your password outside of System Settings
  • Your Mac is managed by a company using Active Directory, Entra ID, or MDM
  • Your password was changed through an identity provider instead of directly on the Mac

When this happens, macOS cannot automatically unlock your login keychain, and you’ll see a prompt asking you to update or reset it.

By default, your Mac login password matches your login Mac keychain password. When you change your password directly in System Settings > Users & Groups while logged in, macOS updates the keychain automatically.

However, if the password is changed externally by an Apple IT administrator or identity provider, the keychain does not update automatically and must be manually synced at next login.

Here’s what those options mean and when to use each one.

What the Keychain Prompt Means

When you log in, you may see a message asking to unlock or update your login keychain. You’ll typically have three options:

Continue Log In

This allows you to proceed without unlocking the keychain. However, you’ll continue receiving prompts until it’s fixed.

Update Keychain Password

Choose this if you know your previous Mac login password. You’ll enter your old password once, and the keychain will sync to your new login password.

Create New Keychain

If you don’t remember your old password, you’ll need to create a new keychain.

This removes saved credentials stored in the old login keychain, including WiFi credentials, VPN settings, and some application passwords.

 

How to Manually Update the Login Keychain (If You Know the Old Password)

If the automatic prompt does not appear, you can update the keychain manually.

  1. Open Finder
  2. Go to Applications
  3. Open Utilities
  4. Launch Keychain Access

Or press Command + Space and search for “Keychain Access.”

Then:

  1. Select login in the left sidebar
  2. In the top menu bar, click Edit
  3. Choose Change Password for Keychain “login”
  4. Enter your old password
  5. Enter your current Mac login password
  6. Click OK

Once updated, the keychain should unlock automatically going forward.

How to Reset the Default Keychain (If You Don’t Know the Old Password)

If you do not remember your previous login password, the old keychain cannot be recovered.

To create a new one:

  1. Open Keychain Access
  2. In the menu bar, click Keychain Access
  3. Select Settings
  4. Click Reset My Default Keychain

macOS will create a new login keychain tied to your current password.

Important: You will need to re-enter saved WiFi passwords, VPN credentials, and some application logins.

 

What About the New Passwords App in macOS Sequoia?

Starting in macOS Sequoia, Apple introduced a standalone Passwords app. This manages website and app credentials synced through iCloud Keychain.

However, system-level credentials such as WiFi passwords, certificates, and some enterprise credentials are still managed through the login keychain in Keychain Access.

If you are experiencing repeated system prompts, the fix still requires updating or resetting the login keychain as described above.

If Your Mac Is Managed by Your Company

If your device is company-managed, password resets may come from:

  • Microsoft Entra ID
  • Active Directory
  • MDM policies
  • Identity providers

In these environments, resetting your keychain may not fully resolve the issue. Contact your IT provider before deleting keychains on a managed device.

Conclusion

Keychain prompts after a password change are common, especially when passwords are reset outside of macOS System Settings. Updating the login keychain with your old password is the cleanest fix. If that’s not possible, creating a new keychain will resolve the issue, though saved credentials will need to be re-entered.

If you’re using a managed Mac or continue seeing prompts after resetting the keychain, your IT services provider may need to investigate deeper credential or directory sync issues.
