It is one of the most maddening Mac annoyances: a banner keeps telling you to enter your Apple ID password — and there is nowhere to type it. No input box, no dialog, just a demand you cannot satisfy. Chasing the banner never works. Here is the real fix: handle it through your Apple ID pane in System Settings, where the legitimate prompt actually lives.
Step 1: Don’t chase the banner — open your Apple ID profile directly
Ignore the floating banner itself. Instead, open System Settings and click your Apple ID profile at the top of the sidebar. The genuine “Update Apple ID Settings” request appears inside this pane — not in a random pop-up — so this is the only place where signing in actually counts.
Step 2: Sign out of iCloud, restart, and sign back in
If the Apple ID pane shows a stuck “Update Apple ID Settings” notification that will not clear, do a clean re-sign: click Sign Out of iCloud, restart the Mac, then sign back in with your Apple ID. This resets the authentication state and clears the loop that keeps spawning the phantom prompt. Signing back in fresh also re-establishes iCloud services like Messages — see how to set up message sync between iPhone and Mac once your account is healthy again.
Step 3: Check Apple System Status
Before assuming something is wrong on your Mac, visit apple.com/support/systemstatus. An Apple ID service outage can trigger exactly these phantom password prompts; if Apple ID shows yellow or red, there is nothing to fix on your end — wait it out and the prompts stop once Apple restores the service.
Step 4: Install pending macOS updates
Authentication glitches are routinely fixed in newer builds. Open System Settings → General → Software Update and install anything waiting. A stale macOS version with a broken sign-in flow is a common root cause of the no-input-window loop. Apple’s support documentation covers managing your Apple ID and iCloud sign-in on Mac in more depth.
Step 5: Reset your Apple ID password from another device
If nothing above helps, reset your Apple ID password from a trusted device via iforgot.apple.com, then sign in again on the Mac. One safety note: the real prompt never asks for a password inside a random pop-up banner. If a banner demands your password but offers no proper sign-in window, never type it there — that is a classic phishing pattern. Always handle credentials inside System Settings → your Apple ID profile.
If it still doesn’t work
Run through the order again: System Settings → Apple ID profile, sign out and restart, check Apple System Status, update macOS, reset the password from another device. MacRumors has covered recurring iCloud authentication bugs across macOS releases, and their forums are a good place to check whether others are seeing the same loop.

Frequently asked questions
Is this a phishing attempt?
Not necessarily — a stuck sign-in state causes genuine prompts to appear this way. But the rule holds regardless: never enter your password into a random banner. Handle sign-in only inside System Settings → your Apple ID profile, where Apple shows the legitimate “Update Apple ID Settings” request.
Will signing out of iCloud delete my files?
Signing out can remove synced data (like iCloud Photos or iCloud Drive copies) from the Mac’s local view, but it stays in iCloud and returns when you sign back in. To be safe, let iCloud finish syncing before you sign out.
Conclusion
Do not fight the banner — bypass it. Open System Settings → your Apple ID profile, re-sign into iCloud after a restart, and the phantom password prompt goes away. And remember: your password belongs only in Apple’s own sign-in panes, never in a pop-up.
