Feeling overwhelmed by keeping your online accounts secure? Authentication is a perfect two-factor authentication (2FA) solution for all your accounts. Very easy to use and 100% secure. Two-factor authentication (2FA), adds an extra layer of security to your online accounts. Authenticator employs a cutting-edge security method called Time-Based One-Time Password (TOTP) to generate unique codes. These codes change every 30 seconds, ensuring that even if someone intercepts one code, they cannot use it to gain access. This two-step autentication significantly reduces the risk of unauthorized access, even if your password is compromised. Key Features: - Strong Two-Factor Authentication (2FA): Safeguard your accounts with the industry-standard TOTP method. - Offline Capability: Continue to protect your accounts even without an internet connection. - Password Management: Securely store and autofill your passwords for effortless logins. - Import/Export Accounts: Easily manage your 2FA accounts through QR codes or private keys. - Wide Compatibility: Works with thousands of popular online services. Why Choose Authenticator? - Enhanced Security: secures all your online accounts on your device by 2-step verification. It generates a unique time-based one-time password (TOTP) for each login, ensuring that only authorized users can access your account. - Convenience: Save time and frustration by eliminating the need to remember complex passwords. Authenticator's password management feature securely stores your credentials for quick and easy logins. - Flexibility: Whether you're at home, work, or on the go, Authenticator's offline functionality ensures uninterrupted protection. - Data Protection: Your account information is securely stored and encrypted, safeguarding your privacy. - Time-Saving: Quickly add new accounts by scanning QR codes or entering private keys. You can authenticate your identity quickly, allowing you to access your accounts without unnecessary delays. - Universal Compatibility: Enjoy peace of mind knowing Authenticator works seamlessly with your favorite online services. Whether you use Google, Instagram, Facebook, Twitter, LinkedIn, Dropbox, Snapchat, Github, Tesla, Coinbase, or even manage your Bitcoin wallet, Authenticator’s 2FA tokens are universally accepted. - Free: Authenticator is completely free to download and use. The app is designed to be accessible to everyone, ensuring that you don’t have to compromise on security due to cost. Why you should use Authenticator's TOTP? Authenticator utilizes Time-Based One-Time Password (TOTP) technology, offering several advantages over traditional SMS-based 2FA: the secret key input for TOTP is only shared once and the method does not rely on the telephony network, which helps reduce the attack surface. TOTP has stronger proof of possession than SMS, which can be legitimately accessed via multiple devices and may be susceptible to SIM swap attacks. Don't compromise your online safety.

FactorCat is a modern authenticator that replaces the code-copying ritual with a single tap. How it works: Install the browser extension on your computer. When you hit a login page that needs a code, FactorCat sends a push notification to your phone. Tap approve, confirm with Face ID or fingerprint, and the code fills in automatically. No switching apps. No squinting at timers. No mistyped digits. Security you can trust: Your TOTP secrets are stored on your device, encrypted and protected by biometrics. FactorCat never holds your passwords — MFA and passwords stay separate by design, so there's no single point of failure for your online identity. Two vault types: • Cloud Vault — cloud-managed keys for easy recovery. Great for getting started with MFA or for low-risk accounts. FactorCat can generate codes on your behalf when your phone is offline. • Locked Vault — zero-trust encryption using a model trusted by leading security products. You hold the keys. FactorCat cannot read your secrets. Backup via encrypted cloud blobs recoverable only with your emergency kit. Getting started takes 2 minutes: 1. Download FactorCat 2. Add your first token (scan a QR or let the browser extension capture it) 3. Pair with the extension via one QR scan 4. Done — your next login fills itself in Also works standalone. Use FactorCat as a regular authenticator with no account or extension required. When you're ready for auto-fill, pair up anytime. Free to use. No ads. No tracking.
