**Backport:** https://codeberg.org/forgejo/forgejo/pulls/7251
Failing the migration when a corrupted record is found is problematic because there is no transaction and the database may need to be restored from a backup to attempt the migration again, after deleting the corrupted records.
Each documented case of failed migration was resolved by removing the corrupted records. There is no instance of a failed migration that was caused by non corrupted record.
In the unlikely event of a false negative where a two_factor record is discarded although it is in use, the only consequence is that the user will have to enroll again. Detailed logs are displayed so the Forgejo admin can file a bug report if that happens.

TOTP is no longer required to login with the associated users. They should be informed because they will need to visit their security settings and configure TOTP again. No other action is required.<!--description-->
