# Using Multi-factor authentication
Learn how to use multi-factor authentication tools to securely access your instance.
## Login with MFA
ServiceNow requires authenticator applications that support Time-based One-time Passwords \(TOTP\). ServiceNow tests MFA with the following authenticators:
- Google Authenticator
- Microsoft Authenticator
- LastPass Authenticator
- Authy
- FreeOTP
- Duo
- Okta Verify
**Note:**
- Other authenticators not listed might also be compatible, but are not tested by ServiceNow.
- For information related to browser specific behavior change, see this [KB article](https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB0998122).
## Register an authentication app
|
- **Authenticator App**
You can use authenticator apps to use a second factor of authentication.
|
If your administrator has enabled multi-factor authentication \(MFA\) on your instance, you are prompted for a second authentication after entering your user name and password. For details on the MFA login process, see [Log in with Multi-factor Authentication](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/platform-security/authentication/t_LogOnWithMultifactorAuth.md).
|
|
- **Validation with Authenticator app**
Enter the code displayed on your authenticator app to login.
|
If you haven't configured a second form of authentication, you will see a configuration page after logging in to guide you through the process of setting up an authentication app. For details on this setup, see [Set up Multi-factor authentication for the first time](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/platform-security/authentication/t_SetUpMultiFactorAuthUponLogin.md).

## Register an authentication device
|
After you've configured an authentication app, you can register other methods for authentication.
- **Biometric authenticators**
You can use biometric authenticators like fingerprint or facial recognition as your second MFA authentication. If your administrator allows this option, you can configure biometric authenticators using the steps in [Register a biometric authenticator](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/platform-security/authentication/mfa-setup-bio-auth.md).

- **Hardware key authenticators**
Hardware keys are physical security devices you can use for authentication. You can register a hardware device for use with your instance using the steps in [Register a hardware security key](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/platform-security/authentication/mfa-setup-hardware-key-auth.md).

|
- **Validation with Biometric or Hardware Key**
Use the biometric or hardware key to login.

|
## Register a phone number for OTP
|
- **SMS**
Use SMS based OTP to require users who attempt to login.
|
When users attempt to login to ServiceNow, SMS OTP is sent to the mobile number associated with the sys\_user record. Users can enter the six-digit verification code that it sent to the mobile device and verify their identity.
\[Omitted image "sms.png"\] Alt text: SMS.
|
|
- **Validation with SMS**
Use the validation with SMS to login based on the OTP generated.
|
You need to enter the 6-digit code sent to the mobile number to login. The code sent is valid for the next 5 minutes. You can use resend code to again send the code.
|
## Register an Email address for OTP
|
- **Email address**
Use Email based OTP to require users who attempt to login.
|
When users attempt to login to ServiceNow, Email OTP is sent to the email address associated to the user. User's can enter the six-digit verification code that it sent to the mobile device and verify their identity.

|
- **Validation with Email**
Use the validation with Email to login based on the OTP generated.
|
You need to enter the 6-digit code sent to the email address to login. The code sent is valid for the next 5 minutes. You can use resend code to again send the code.\[Omitted image "email-screen-mfa.png"\] Alt text: MFA-Email.
