## Google Sign-In

Contafy supports Google Sign-In for faster authentication without managing passwords.

### First-time Google Sign-In

When you sign in with Google for the first time:

2. Select your Google account
3. Grant Contafy permission to access your basic profile information
4. Your account is automatically created and verified
5. You're redirected to your dashboard

<Note>
  Google accounts are automatically verified and don't require email verification.
</Note>

## Security best practices

To keep your account secure:

* **Use a strong password**: Combine uppercase, lowercase, numbers, and special characters (minimum 8 characters)
* **Don't share credentials**: Keep your login information private
* **Log out on shared devices**: Always log out when using public or shared computers
* **Monitor account activity**: Review your recent activity regularly

## Troubleshooting

### "Email y contraseña son requeridos"

Both email and password fields must be filled. Check that you've entered information in both fields.

### "Error al iniciar sesión"

This generic error can occur due to:

* Incorrect email or password
* Network connectivity issues
* Server maintenance

Double-check your credentials and try again. If the problem persists, use the password reset feature.

### "Email no verificado"

Your email address hasn't been verified yet. Check your inbox for the verification email or request a new one from the verification page.
