Two-Factor Authentication (2FA) adds an extra layer of security to your net2phone account by requiring a second verification step when you sign in. In addition to your password, you must confirm your identity by entering a temporary verification code sent to you via a secondary, separate method. Once 2FA is enabled, all users will be prompted to verify their identity every time they log in to their account.
Why implement 2FA?
2FA helps protect your account even if your password is compromised. Passwords alone can be guessed, reused, or exposed through data breaches. Two-Factor Authentication reduces the risk of unauthorized access by requiring something you have (such as your phone or email) in addition to something you know (your password).
In some organizations, administrators may require Two-Factor Authentication for all users.
If 2FA is enforced at the company level, you’ll be required to complete setup before continuing to use your account. Administrators can also assist with resetting 2FA if access is lost.
Available 2FA Methods
The net2phone system supports multiple authentication methods. You can enable one or more options and choose which method to use when signing in.
Using Multiple Methods
If you enable more than one 2FA method, you’ll be prompted to choose which method to use each time you log in; this flexibility can be helpful if one method is temporarily unavailable.
Authenticator App (Recommended)
Use a Time-based One-Time Password (TOTP) authenticator app to generate secure login codes.
- Examples include Google Authenticator, Authy, and Microsoft Authenticator.
- Works even without cellular service.
- Provides the strongest level of account protection.
SMS Authentication
Receive a one-time verification code by text message on your mobile phone.
- Requires access to your mobile device.
- Delivery depends on mobile carrier availability.
Email Authentication
Receive a verification code at the email address associated with your account.
- Uses your account email on file.
- Often used as a default or fallback method.
Change your 2FA Method
Two-Factor Authentication (2FA) adds an extra layer of security to your net2phone account. If your company allows it, you can switch between available 2FA methods in the Company Settings portal.
Changing your 2FA method only affects your personal login. Administrators may lock certain methods as the company's default.
Access the Settings Portal
- Click your profile icon in the top right corner of the app.
- Select Company Settings.
You will be redirect to a new browser tab.
Open Two-Factor Authentication Settings
- In the left-most navigation menu, click the gear icon for Settings.
- Click Two-Factor Authentication.
- You’ll see the list of available methods:
- TOTP Authenticator App (e.g., Google Authenticator, Authy)

Recovery Codes
When you finish setting up Two-Factor Authentication, you’ll receive a set of recovery codes.
These codes allow you to access your account if you lose access to your authentication method (for example, if you lose your smartphone).
- Download, copy, or print your recovery codes and store them securely.
- Each code can only be used once.
- You can generate new recovery codes at any time from your 2FA settings.
