Login Keychain Password Lock will not persist
MacOS 10.15.2 Catalina.
If I go to Access Keychains and click on File, Lock All Keychains it will lock the login password keychain as expected. The padlock icon changes to locked.
Next time I log into (say) my webmail in Safari it askes for the password.
It then concurrently unlocks the keychain. Padlock icon reverts to open.
Is this normal?
I have the same password for User Login as I do for Keychain.
In contrast, my Ipad will keep asking for the password as I would expect it to when logging into accounts that require Keychain.
