Legacy Enhancements: Wait time & View only Mode

[anon221218]

I see "Legacy" has been added to Ente Photos, so hopefully "Emergency Access" will come to Auth soon too;
but I'd hope when it does, that it

1. has the ability to set a custom allow/deny duration (like Bitwarden does)
   and it would also be nice to have
2. the option to allow a "View Only" rather than takeover mode (as Bitwarden does).

While these features aren't needed very much for a photo library, they are more important for a credentials manager.

This would be useful, for example, if the account owner was temporarily unable to handle their affairs for some reason (travel, medical, etc) and needs their trusted contact to take care of them on their behalf in the meantime (without needing to wait 30 days or basically handing over their account).
