Hello L4popi,
Welcome back to Apple Support Communities!
We're glad you're able to login without any issue. We suggest making sure the macOS is fully updated to help resolve any potential software issues. You can use these steps:
"Use Software Update
Before installing new software, it's a good idea to back up your Mac.
- From the Apple menu in the corner of your screen:
- Choose System Settings. Then click General in the sidebar, and Software Update on the right.
- Or choose System Preferences. Then click Software Update.
2. If Software Update finds new software, click the Update Now or Upgrade Now button to install it.
3. Enter your administrator password, if asked. During installation, your Mac might restart, and you might see a progress bar or blank screen several times.
If Software Update says that your Mac is up to date, then no new software is currently available for your Mac model. Software Update shows only updates and upgrades that are compatible with your Mac."
We hope this helps to resolve any issues that might have caused the prompt for the login screen and your password.
Cheers!
