Mac os High Sierra cannot save password
I just upgraded to High Sierra 10.13 recently and encounter serious password problem, every time I on the Mac from sleep mode or reopen the app, it prompts up a sign-up/sign in screen, my app login credentials are missing, it happens to Evernote, Coda, Transmits and some other apps.
For app like Coda, Transmits, all saved FTP password are blank, it just cleans up each time I reopen the app, you can't imagine how troublesome have to search for each FTP password and enter one by one, this never happen before I upgraded to latest OS.
icloud also have the problem to access, it asks the password each time I tried to access icloud from system Preference, and I am sure I key in the right password but the unknown error occurred.
I already reformat and reinstall the mac but some problem occurs.
iMac, macOS High Sierra (10.13)
