Memmy - An iOS client for Lemmy

I would like to ask if it possible to have Face ID lock and the show the display name.

So not the name you made when making an account but the second one, to show. Currently (at least for me), it shows the account name instead of display name.

Would also like to ask is there any way to donate a few bucks to you? This app has been insanely good and I’m assuming, you’re making this in your free time without anything in return.
