Website passwords in keychains deleted after Catalina update
After upgrading to Catalina, the website passwords -- but not app passwords, secure notes, certs, or keys -- were deleted from all keychains in `~/Library/Keychains`. Keychains stored elsewhere were not affected.
I use different keychain files for different purposes (personal, work, etc.). Many but not all of these are stored in `~/Library/Keychains`. I can see in the filesystem modification time that all the keychains in there were updated as of the time I upgraded to Catalina although many of these keychains haven't been unlocked in months. It seems there must have been some process as part of the upgrade that deleted things.
I ran the unix utility `strings` on the keychains which usually can reveal the names of items in a keychain database file. Unfortunately, it looks like the passwords in question have been completely deleted.
Notes:
- MacOS Catalina 10.15
- MacBook Pro (Retina, Mid 2012)
- Safari Version 13.0.2
- iCloud *not* used to sync the keychain
