If you change the mailbox's password with your mail provider, or need to adjust any other connection detail, use **Reconfigure credentials** on the panel of an already-connected channel (section 7). **Requirements:** administrator role. 1. Tap **Reconfigure credentials**. 2. The form reloads with the already-saved non-sensitive data (address, servers, ports, username…); the **Password** field always starts **blank**. 3. Change whatever you need. 4. Test the connection again (section 6) and tap **Save and connect**. > **Warning — Blank password means don't change it** > > If you only need to touch another field (for example, the display name) and the password stays the same, > **leave it blank**: the Platform never shows it again once saved, and an empty field explicitly means > "keep the already-saved password", never "clear it". Only type a new password if it has actually > changed.
