AuthNull Authenticator

AuthNull

About this app

AuthNull Authenticator is the companion app for the AuthNull identity and privileged access platform. When you sign in to a system your organization protects with AuthNull, your phone gets a request. Approve it with one tap, or deny it if it wasn't you.

Works with:
• Windows and Active Directory sign-ins
• VPN (RADIUS) logins
• Database access
• Privileged password reveal
• The AuthNull console and connected apps

Approve from anywhere
• Approve or deny straight from the notification
• See what is being approved before you answer: the system, the user, the location and a risk level
• Number matching: tap the number shown on your sign-in screen, so a request you didn't start can't be approved by mistake
• Requests answered on another of your phones clear automatically

Secured by your phone's hardware
• Every approval is signed with a key created in your phone's secure hardware. It never leaves the device.
• Optional fingerprint or face check on every approval
• App lock with a 6-digit PIN, and unlock with your fingerprint or face

One person, many places
• Use the same account across several tenants of your organization
• Add up to 10 phones to your account, and sign out any of them from Settings › Devices
• Get an alert when a new phone is added to your account

Easy to set up
• Scan the QR code from your invite, open the invite link, enter an activation code, or sign in to your organization (including single sign-on)
• Works with AuthNull cloud and on-premises servers, including private servers reached over VPN

One-time codes
• Add six-digit one-time codes (TOTP) for other services. The secrets stay on your phone.

AuthNull Authenticator needs an account from an organization that uses AuthNull. Ask your administrator for an invite.
