Can I add two-factor authentication to my account?
Yes — from your profile you can turn on an authenticator app, emailed one-time codes, or both, with backup codes as a fallback.
Your profile page has a two-factor section. You can enable an authenticator app (Google Authenticator, 1Password, Authy and similar), one-time codes emailed to you at login, or both.
Either way you're given a set of single-use backup codes. Keep them somewhere other than the phone you authenticate with — they're what gets you back in if you lose it.
You're emailed whenever two-factor is turned on or off, so a change you didn't make doesn't pass unnoticed.
