## What is 1TP?

A SECURE LOGIN HAS NEVER BEEN SO EASY!

Would you like to log into your services more securely? Two-factor authentication is essential for this. After entering the user name and password, a so-called one-time password is required. 1TP generates exactly these passwords for you. Easy, safe and fast!

UNLIMITED ACCOUNTS POSSIBLE

You can store as many accounts as you need in 1TP. Whether email tool, game access or development console. In 1TP, a secure one-time password is generated for almost every service.

FULLY COMPATIBLE WITH RFC 4226 and RFC 6238

1TP generates both time- and counter-based passwords with 6 or 8 characters for you. You can store various encryption algorithms and control the time interval for time-based passwords. The additional option of time synchronization also ensures that correct passwords are calculated every single time.

MANUAL ENTRY OR QR-SCAN POSSIBLE

You can easily scan new accounts via QR code or enter them manually and configure them in detail. A new account can be added in less than a minute.

FAST, SIMPLE AND CLEAR

You can store different text fields and choose from a large selection of service icons to find your accounts faster. You can also mark frequently used accounts as favorites and of course sort your lists in different ways. This is how you can find the account you are looking for particularly quickly.

HIGH SECURITY AND NO DISCLOSURE OF DATA

Of course, your accesses are well protected here. You can protect all accounts with Face ID or Touch ID and there is no app tracking, no in-app advertising and of course no disclosure to third parties. Also, we do without analysis tools that are often used to improve apps, so that you can be completely unconcerned.

FURTHER FUNCTIONS COMING SOON

Your access passwords also on the Apple Watch or as a home screen widget? Coming soon, we are already busy working!
