Many apps require or are compatible with signing via my email address on Cloudron (sogo, nextcloud, etc). The trouble is some require using my username. This becomes troublesome when my password manager only remembers one or the other. I can work around this, it isn't the worst. I'm wondering if there's a way to fix it so apps can consistently use one or both. Thanks.
@moonmeister I think it's better to use the username for login into all apps except the email apps like roundcube/rainloop/sogo (because they require email to know which mailbox to open).
The email login was probably not a good idea to start with because the email can be changed unlike the username. These days when we bring in new apps, we don't bother much with email login.
