These might be good, but since most people use Google Authenticator for storing their 2FA tokens, most platforms and apps use that as well. I believe that will be an easier choice and the majority will agree to this because if you already have Google Authenticator, you would want to use that for a new platform instead of having to download another authenticator app for only one platform.
This is not a big deal like anyone can go for what’s best besides Google Authenticator is pretty good but going for something else all depends on what’s available. Let’s watch what the project team will decide concerning the 2FA application.
Talking about security, I was thinking that maybe there could be another thing implemented as well. It's called a Fund Password. I have seen it in most of the centralized exchanges. It's basically a password or a PIN that you set which you can use when you are making transactions such as withdrawals. Maybe adding this along with 2FA can be a great addition. Just a suggestion, it's up to the team to decide.
It’s kinda interesting for security purpose and I think it’s good aside other centralized platform, this idea is so common in most platforms including exchange, banking platforms etc it’s either an ID or PIN. I fully know the team knows what’s best and they’re doing every possible best to create a good platform for everyone.
