Passera – Generate A Unique Strong Password For Every Website


We’ve discussed password storage/generation solutions quite often, especially in the news stories about hacks and plain text password leaks, here’s a tool for the more paranoid who don’t want to store their passwords locally or in the cloud.

Passera is a simple tool written in Go that allows users to generate a unique strong password for each website, without the need to store them either locally or with an online service.

Passera - Generate A Unique Strong Password

Passera turns any entered text into a strong password up to 64 characters long and copies it to clipboard. Figure out a decent system for yourself that will allow unique passphases for every website, such as combining website name/url with a phrase that you would not forget. To login, fire up Passera and enter the password you chose and your real password will be copied to the clipboard.

This software is for privacy-aware people that understand the need to have strong unique passwords for each website, yet don’t want to use any password managing software or services. Relying on password managing software means trusting your passwords to be kept safe by a third-party company, or trusting them to a single file on your disk.

Passwords created with Passera are extremely difficult to bruteforce and impossible to revert back to the original regardless of attacker’s knowledge of the source code. If one of your passwords is compromised after an attack on you or a web service, all your other passwords are safe with you.

To make it somewhat more conspicuous, when you start Passera it copies a random password to clipboard. The real password is then only stored in clipboard for 10 seconds, before being overwritten by another random string.

You can download Passera here:

Linux
Mac OSX

    Maybe it’s a noob question, but where I store these password? do I have to use passera in combination with keepass?

      You don’t store the passwords, you use Passera to generate them when you login using your passphrase. This is to avoid using any storage system (if you are that paranoid).

    Hi, I run Passera for Win 386, I get these:
    1) I cannot run Command-line tool – I tried all the way – no results, I do not get dollar sign, so I wrote the line myself, but as soon as I hit enter program start count down (has generate a Pw)
    2) generate pw are always 13 characters, and it is not related to the lenghts of my phrase.

    It would be fine if at least can generate 16 characters.

    Thank you for your attention,
    Best Regards,
    Marco

    Very nice.

    I also like the solution at http://www.passwordchart.com

    They don’t store anything, they just generate a useful series of passwords from your own more readable strings.

    The only real advantage that this solution has over your solution here is that if I can get a web connection I can generate all my passwords as required, without having to install software locally.
