Logging into trello is already bad, having to enter email address first, then click, then the password.
But what really annoys me is the 2 factor authentication nag screen that follows after logging in.
I have 0 interest in using 2FA for trello. You know who I am after logging in, so please make this a decent setting un the user profile, like: don't bother me with 2FA
Or respect the current setting: Not using 2FA
