Extension summary


Since 1Password is unhappy about the previous name of my extension, a.k.a. OnePassword, and threat to sue me in the court. I'm going to rename this to 123 Password.

I hope they haven't spent a lot of money on their lawyer for this.


123 Password generates a different strong password for each site you visit by mixing: a) your master key, which you create by yourself, and b) a site key, which is automatically extracted from site URL.

With 123 Password, you only need to remember your master key. The extension will give different passwords on different websites. The algorithm (HMAC + MD5) makes it very hard to guess your other passwords, even if one of them is compromised. The extension NEVER store any password key for you, so that security is protected even in case of hardware theft.

The strong passwords generated by this extension are 20-characters long and consist of A-Z,a-z, and 0-9. You can resize the password for different sites and the extension will remember your settings.

Ea importante contar con la seguridad de privacidad y funcionamiento del equipo de manera segura.

I have no idea why this extension has so few reviews. I use it daily for years, it works like it should, perfect to handle 50+ site passwords with just one simple password. Highly recommended!
