Password – Threema. The Secure Messenger Review

I don’t understand why in an upgrade some time ago they took away the letters under the numbers (as on a telephone) and never put them back. For me this makes it harder to use because I remember letters more easily than numbers, hence I have to look up my password, hence I use less.
