Activating two-factor authentication (2FA) on your account

What you need to know about 2FA

• 2FA is mandatory on Zeffy. To keep your account secure, you must set up two-factor authentication to access the platform.

• 2FA is user-specific. If multiple people have access to your Zeffy account, each user must set up 2FA for their own email address. Enabling 2FA for yourself won't affect other users.

• 2FA uses your phone number. Every time you log in, you'll receive a 6-digit code via text message that you'll need to enter to access your account.

Setting up 2FA

When you log in to Zeffy for the first time (or if you haven't set up 2FA yet), you'll be prompted to add your phone number:

1. Enter your phone number when prompted. See the list of supported countries here. 
2. Click Send code to receive a 6-digit code via text message
3. Enter the code you received and click Submit
4. Once verified, you'll see a green "Active" banner confirming 2FA is enabled

Your phone number is only used for account security — we won't send you marketing messages or use it for any other purpose.

Logging in with 2FA

Once 2FA is set up, here's what to expect each time you log in:

1. Enter your email and password as usual
2. If we recognize that there is something different about your login, you'll receive a 6-digit code via text message to your phone
3. Enter the code on the login page (codes expire after 15 minutes)
4. You'll be directed to your Zeffy dashboard

Managing your 2FA settings

To view your 2FA settings:

1. Log in to your Zeffy dashboard
2. Click on your name in the top left, then select Settings
3. Click on Two-factor authentication in the account options

On this page, you'll see:

• The last 4 digits of your registered phone number
• Your 2FA status (Active)

To change your phone number: Email us at contact@zeffy.com and we'll help you update it.
