Two-factor authentication

Two-factor authentication (2FA) adds a second step to your login, so a stolen password is not enough to get into your account. It is available on all plans.

Enable 2FA

1. Go to Settings, then Security.
2. Click Enable Two-Factor Authentication.
3. Scan the QR code with your authenticator app. Google Authenticator, Authy and 1Password all work.
4. Enter the 6-digit code your authenticator app shows to verify it.
5. 2FA is now enabled for your account.

Save your backup codes somewhere secure while you are here. If you lose access to your authenticator app, a backup code lets you log in and reset your 2FA settings.

Logging in with 2FA on

1. Enter your email and password as usual.
2. Open your authenticator app.
3. Enter the 6-digit code shown for Underpriced AI.
4. You are in.

The code changes every few seconds, so if it is rejected, wait for the next one and try again. Your account is the same on every device, so the same code process applies whether you are on the web, the iOS app or the Android app.

Disable 2FA

Go to Settings, then Security, and click Disable 2FA. You will need to enter your password and a valid authenticator code to confirm. You can enable it again later at any time with a fresh QR code.

Codes by text are not us

If you are asked to verify a phone number by text during checkout, that prompt comes from Stripe Link, our payment processor, not from Underpriced AI. It is optional and skippable: enter your card details directly to finish. We never require phone verification, and we do not see or store your phone number from that step. Our 2FA uses an authenticator app only.

While you are thinking about security: platform connections such as eBay use OAuth, so we never see or store your marketplace passwords, and your images are stored in encrypted AWS S3 storage.
