2FA adds a second verification step at login. Even if someone knows your password, they cannot access your account without also passing the second check. EsusuOnline supports four 2FA methods — choose the one that suits you best.
Google Authenticator, Authy, Microsoft Authenticator — works offline
RecommendedOne-time code sent to your registered mobile number
Six-digit code sent to your account email address
Hardware key, Touch ID, Face ID, or Windows Hello (WebAuthn)
Click your profile avatar (top-right) and select Security & 2FA,
or open the sidebar and choose Settings → Security & 2FA.
The URL will be esusuonline.org/security/2fa.
The page has four tabs — one per method. Select Authenticator (active by default), then click "Set Up Authenticator".
A dialog appears with a QR code. Open your authenticator app, tap "+" or
"Add account", choose Scan QR code, and point the camera at the code.
If you can't scan, tap "Can't scan? Enter key manually" and type the secret key shown below the QR code.
After adding the account in your app, a 6-digit rotating code appears (refreshes every 30 seconds). Type it into the verification field and click "Verify & Activate".
After successful verification, 10 single-use backup codes are displayed. Save them somewhere safe (password manager, printed paper) — you'll need one if you ever lose access to your authenticator app.
The Security page now shows your 2FA status as ON with your enabled method listed.
Click the SMS tab, enter your mobile number in international format (e.g. +2348012345678), and click "Send Code".
Check your phone for a 6-digit code. Enter it in the verification field (code expires in 5 minutes) and click "Verify".
EsusuOnline sends a 6-digit code to your registered email. The code expires in 5 minutes.
Copy the 6-digit code from the email and paste or type it in, then click "Verify".
The login screen looks identical to before. Submit your credentials normally.
After a correct password, EsusuOnline asks for your second factor. Open your authenticator app (or check your SMS/email) for the current code.
