Authenticator App
Your Secure Gateway to Multi-Factor Authentication.
Experience the convenience of one-tap push notifications (COTP) for Comtarsia SignOn Solutions, and manage all your standard TOTP/HOTP accounts for services like Microsoft and Amazon in a single, secure, and intuitive app.
One App for All Your MFA Needs
The Comtarsia Authenticator combines proprietary push technology with industry standards to deliver a superior and versatile security experience.
Effortless Push Authentication
Log in to Comtarsia-secured systems with a simple tap. Our COTP technology sends an end-to-end encrypted notification to your phone for quick, biometric-protected approval.
Universal Standard Support
Don't juggle multiple apps. In addition to COTP, our app fully supports TOTP and HOTP standards, making it your central hub for all 2FA-enabled accounts.
Designed for Privacy & Security
COTP messages are end-to-end encrypted; our cloud service only routes them and cannot read their content. Your security keys and data remain under your control.
