I think "Master Password" as a term is fine.
It's not! I don't think anyone would want to login into an app with something called a "seed" or "account recovery string".
On the other hand, using the word "password" encourages people to do so, which is wrong.
Damn, now it makes sense to me. Since we should not use the master password ever except for account recovery.
We must do this change, especially for security reasons.
I was only thinking about myself but you are right. Other people might use it just because it's more convenient than using multiple keys.
Glad you got it 🤓
