Back in July I enabled two-factor authentication, and set up an app password for use on my devices. Sometime in late November, with no warning, this app password disappeared and a I had to regenerate another one. And now it’s happened again. The time between occurrences isn’t consistent, and there’s nothing in the logs to indicate why this is happening.
Any ideas why? Is there an expiry somewhere, or some other setting to disable app passwords after a certain period of time?
I’m using LDAP for the primary authentication, if it makes any difference.
