Sorry for taking your important time. I was trying to log in using my phone and it was giving wrong password even if i entered the correct password. I saved my account information in my laptop, so i got logged in here. As someone gave new password(I guess), and i dont know that. how to recover the old password??

When I started codeforces (2 months ago), I didn't realize what a handle is? So, now, I want to change my handle. So, 2 questions- 1. Can I change my handle? 2. Comment below some handle name to give? (like a suggestion).
