Bitwarden already uses the otpauth:// schema for storing the TOTP configuration within a login item.
A handler should be added so that an otpauth://… link can be clicked or emitted by another app to easily add that TOTP configuration to a Bitwarden entry.
Yes, I second that.
This is a real gap in Bitwarden’s functionality that I think should be closed ASAP.
It is the very thing that Bitwarden should provide out of the box, at the very least with TOTP code generation that is part of the premium subscription.
