What you’re seeing
- After a password change, the Mac still accepts only the old password at the login screen.
- Constant prompts to update the login keychain, or keychain errors at startup.
- Wi-Fi, email or file shares repeatedly ask for the new password.
- A message saying the network account is unavailable or the password couldn't be synced.
Common causes
Every environment is different, but these are the causes our engineers find most often:
- The Mac uses a local or mobile account that only updates its password when it can reach a domain controller or identity provider at the right moment.
- The password was changed on another device or online while the Mac was away from the network.
- The login keychain is still locked with the old password, so saved credentials can't be unlocked.
- Platform SSO or the Kerberos SSO extension is partially configured and falls out of sync with Entra ID or Active Directory.
- Saved credentials for Wi-Fi, mail or file shares still hold the previous password.
Why it matters
A Mac with mismatched passwords slows its user down all day with prompts, failed connections and keychain errors. Repeated attempts with the old password can lock the account across every system, stopping the person from working on any device. Frustrated users may write passwords down or borrow a colleague's login, eroding security. Handled poorly, resetting the keychain can wipe out saved passwords and certificates the user relies on.

Frequently asked questions
Will the user lose saved passwords?
Not if the keychain is handled correctly. When the old password is known, saved items can usually be kept, and we confirm the situation before touching anything.
Will this keep happening every time passwords change?
It can, depending on how your Macs are tied to your directory. We explain in plain English why it happened and what would prevent it.
