Disclaimer : I am absolute noob in terms of SSH kind of stuffs.

I maded a SSH key on ConnectBot app on android.I still have password of that key.I got a private and public key.I shared public key with tildes for making accounts.Now they know me by my that key but I want to login by termux. On termux I installed openssh and tried to login it says that authentication failed.

So I just need to backup keys from connected bot and restore on termux and my PC . Will it work ? How to do it? Will making a new pair of keys using same pass and name will work?

I did not got anything regarding this on searches
