app_passwords.rs
| 1 | //! App passwords: per-client credentials for WebDAV mounts. |
| 2 | //! |
| 3 | //! One exists so a mount never carries the account password, and so an |
| 4 | //! account that requires a passkey in the browser can be mounted at all. |
| 5 | //! HTTP Basic can only send a password, and [`crate::api::dav`] refuses to |
| 6 | //! quietly downgrade that requirement. |
| 7 | //! |
| 8 | //! A self-service password change leaves app passwords standing, exactly as |
| 9 | //! it leaves the account's passkeys standing. Only an admin reset sweeps |
| 10 | //! them: that one exists to lock a stranger out. For the same reason these |
| 11 | //! routes do not drop the account's other sessions, which every route in |
| 12 | //! [`crate::api::passkeys`] does. |
