Authenticator App – SafeAuth

What is SafeAuth?

SafeAuth is a free Android application developed by SafeAuth Services that creates time‑based one‑time passwords (TOTP) for two‑factor authentication (2FA). By generating a six‑digit code that changes every 30 seconds, the app adds an extra verification step to protect your personal and work accounts.

Main features

• Standard TOTP generation – Works with any service that supports the RFC 6238 standard, such as email providers, social networks, and cloud services.
• QR code scanning – Quickly add a new account by scanning the QR code displayed by the service you are securing.
• Manual entry – Supports adding accounts by typing in the secret key when a QR code is not available.
• Offline operation – Codes are generated locally on the device, so they are available even without an internet connection.
• Biometric or PIN lock – You can protect the app itself with a fingerprint, face unlock, or a PIN to keep your tokens private.

How it works

When you enable 2FA on a website or app, the service provides a secret key, usually presented as a QR code. SafeAuth reads this key and stores it securely on your device. Every 30 seconds the app calculates a new six‑digit code using the stored secret and the current time. During login, you enter the displayed code after your regular password, completing the two‑step verification process.

Practical uses

SafeAuth can be used with a wide range of online services that support TOTP, including email accounts, social media platforms, financial tools, and developer services. By centralising all your 2FA tokens in one app, you reduce the need to carry separate hardware tokens or rely on SMS codes, which are vulnerable to interception.

Installation information

Search for Authenticator App – SafeAuth in the Google Play Store and tap Install. The app requires Android, but the specific minimum version is not listed; it will install on devices that meet the Play Store’s compatibility criteria. After installation, open the app and follow the on‑screen guide to add your first account.

Things to know before installing

• The app is free to download and use.
• All generated codes are stored locally; there is no mandatory cloud backup.
• Because the app does not sync data automatically, consider exporting your token list manually if you plan to change devices.
• Keep the app locked with a biometric or PIN if you share your device with others.

Who may find SafeAuth useful?

Anyone who wants to strengthen the security of their online accounts without purchasing a hardware token will benefit from SafeAuth. It is especially handy for users who travel frequently, need offline code generation, or prefer a single app to manage multiple 2FA tokens.

Frequently asked questions

Is SafeAuth compatible with my existing 2FA accounts?

Yes, as long as the service uses standard TOTP, you can add it to SafeAuth by scanning the QR code or entering the secret key manually.

Do I need an internet connection to generate codes?

No. The app calculates codes locally using the device’s clock, so it works without network access.

Can I protect the app with a password?

SafeAuth offers biometric authentication and a PIN lock to keep your tokens private.

What happens if I lose my phone?

Because SafeAuth stores tokens locally, you should back up the secret keys manually or use a secure method to transfer them to a new device.
