  1. Go to Clerk Dashboard → your application
  2. Navigate to Configure → Email, Phone, Username
  3. Toggle Email address to enabled
  4. Under Authentication strategies, enable Password
  5. Click Save

Users can now sign up and sign in with email and password alongside OAuth providers.

Configuration Options​

Email Verification​

By default, Clerk sends a verification email on sign-up. You can configure:

  • Required verification — Users must verify email before accessing the app
  • Optional verification — Users can access immediately, verify later

Password Requirements​

Configure in Clerk Dashboard → Security → Password:

  • Minimum length (default: 8 characters)
  • Require uppercase, lowercase, numbers, or special characters
  • Block common passwords

Testing​

  1. Navigate to your ProjectAchilles instance
  2. Click Sign Up on the Clerk login page
  3. Enter an email address and password
  4. Check your email for the verification code
  5. Enter the code to complete registration
  6. You should be redirected to the Test Browser

Production Best Practices​

  • Enable email verification in production
  • Set minimum password length to 12+ characters
  • Enable "block common passwords"
  • Consider enabling multi-factor authentication (MFA) for admin accounts
