I've seen this done to mask User ID (which as Hitman mentioned above, indicates plain-text storage, but for a User ID that's OK), but for a Password? I hope I don't run into any systems that use this, especially not financial services companies!
You'd probaby find that using an SSH Access Manager or one of the many free github ones is going to be easier. They all seem to have extra tools for things like rsync.
Edit: sorry just seen how old this was
Came here to request same.
More and more of my apps support all forms of biometric unlock on my Samsung S10+ running Android 10.
Really hope to see Enpass join the ranks soon!
