Technical two-factor authentication

[frozzypix]

Hello, i activated two-factor authentication, and can log in from pc, but when i'm trying to log in from my phone it's warns me that code out of date and new one will be send. And same for every try. If i past code without switching apps on phone (code checked on pc, log in on phone), then there is no any problems also.
Can smb help me?
ps. vedroid 6, miui 8, chrome mobile.

Your browser probably reloads the page when you switch back to it, causing Warmane to send you a new code. I don't know if there are settings to disable it but you can try to find a browser that does not do it.
