Help for entering a different mobile login

Help for entering a different mobile login

I used a friend login to try Kobo, but now that I’ve created an account, I just can not log in with my new login! I tried several ways, but none worked, including uninstalling and reinstalling, but the problem persists!
Can someone help me?!

Hi @cleitonlfj

Did you receive an activation email after you created your new account?
