Two-Factor Authentication (2FA) adds an extra security step to your Titan account by asking for a verification code in addition to your password. This article is for any Titan user who already has 2FA turned on. It shows you how to log in on Web, Android, and iOS, and what to do if you can't access your authenticator app.

Prerequisites
You've already set up 2FA on your account. If you haven't, see Setting Up & Editing your Two-Factor Authentication (2FA) first.
On Android and iOS, update the Titan app to the latest version before you try to log in with 2FA.
Log in on Web
Using your authenticator app
On the login page, enter your Email address.
-
Enter your Password.
Click Login. You'll be asked for a verification code.
-
Open your authenticator app and enter the current code shown for your Titan account.
| alert-success | If your code is rejected as invalid, check that the date and time on your device are set automatically. Authenticator codes are time-based, and a clock that's out of sync is the most common cause of this error. |
You'll be signed in and taken to your inbox once the code is accepted.
Using a recovery code
If your authenticator app isn't available, use one of the recovery codes you saved or emailed to yourself when you set up 2FA.
On the login page, enter your Email address.
Enter your Password.

Disable Two-Factor Authentication
If you've lost access to both your authenticator app and your recovery codes, your account admin can turn off 2FA for you. Only an account admin can do this.
Log in to the Email Control Panel using your admin credentials.
| alert-warning | If you're a Blacknight user, log in to your Email Control Panel using this link instead: https://manage-euc1.titan.email/ |
Find the email account you want to change in the account list.
Click the ⋮ (ellipsis) icon next to that account.
Click Disable Two-Factor Authentication.
2FA will be turned off for that account immediately, and the user can log in with just their email and password.
Confirmation — what success looks like
When you've logged in successfully with 2FA, you'll land directly in your Titan Mail inbox — no further action is needed. If an admin disables 2FA for an account, the ellipsis menu will no longer show a "Disable Two-Factor Authentication" option for that account, confirming the change took effect.
Troubleshooting
My verification code says it's invalid
Problem: The code from your authenticator app is rejected even though you entered it correctly.
Cause: Authenticator codes are time-based. If your device's clock is off, even by a minute, the code won't match.
Fix: Turn on automatic date and time in your device settings, then generate a new code and try again.
I don't have my authenticator app or my recovery codes
Problem: You can't complete either login method.
Cause: Both 2FA methods on your account are unavailable to you.
Fix: Contact your account admin and ask them to disable 2FA for your account, following the steps in Disable Two-Factor Authentication above. You can then log in with just your email and password and set up 2FA again.
I can't find the "Use recovery code instead" option
Problem: The recovery code link isn't visible on the login screen.
Cause: This option only appears after you've entered your email, password, and clicked Login — it won't show up before that.
Fix: Enter your email and password and click Login first, then scroll down on the verification screen to find Use recovery code instead.
