Two-step verification is a tool that provides an extra layer of security for your online Square Dashboard, protecting your account from unauthorized access. All you'll need is a U.S. mobile phone number. With two-step verification, you'll be asked to enter the verification code (that you'll receive via text) every time you sign in to your online Square Dashboard.
1. Sign in to your online dashboard and navigate to Account & Settings.
2. Click “Activate 2-Step Verification.”
3. Add your primary mobile phone number, then click “Next.” You’ll then receive a verification code via text.
4. Enter the verification code in the field on your dashboard.
5. Click “Verify.”
If an account has 2-step verification enabled, employees, new and existing, will be required to set up and use 2-step verification to access the online dashboard.
Note: Only employees with dashboard access permissions will be required to set up 2-step verification.
After 2-step verification is enabled on an account, Square will email existing employees with instructions on how to complete setup. If employees don’t turn on 2-step verification after reading the email, they’ll be required to do so the next time they try to sign in to the online dashboard.
New employees (with permissions to access the dashboard) will automatically see 2-step verification setup when they create a new employee account.
