How to set user name on termux

[skydivingwill]

I was looking for how to set username so I could use ssh to other servers with this app.
I saw several closed posts here that say it's not possible but it actually is.

• open Termux app
• create text file with: nano .ssh/config
• add the follow text:
  Host *
  User YourUserName

For SSH this can be done using ssh myusername@myhost or changing ~/.ssh/config as you said.

But it is not possible to change your actual user name under which you logged in to Termux, i.e. the one reported by id (like u0_a123). This name is generated on the fly by libc from number of parameters (device user id, runtime Linux user id) when when resolving user properties through getpwuid() function or similar.
