TL;DR – Master Password is not another password manager. This app will replace all your passwords with new strong passwords generated from your new master password; passwords are stored nowhere and need no sync, cloud or backups.

This app will securely generate strong and unique passwords for any purpose, in a way that nobody can log or trace.

Better yet, even if you somehow lose everything, you can effortlessly recreate all your passwords.


WHY MASTER PASSWORD?

Master Password is unique in the way it solves the password problem.
The algorithm it uses was specifically designed to combat the drawbacks other password managers suffer from:

• Vault apps (eg. 1Password): You need to sync and make backups to avoid losing everything. Without access to the vault, no passwords.
• Cloud apps (eg. LastPass): You need to trust they haven't and won't get gagged and compelled to spy on you. No Internet, no passwords.

By using a unique cryptographic algorithm, Master Password generates the password for your site ON-DEMAND, completely OFF-LINE and using nothing but your name and master password.

That means your passwords are not stored on your phone, there's nothing to keep in sync, no reliance on a third party, no need for syncing, copying or backing up. If your phone gets stolen or confiscated, there are no passwords in the app.

Master Password can also:
• Generate a user name for your sites, so you can't forget it or to provide additional anonymity.
• Generate answers to security questions, so you don't need to share your private life experiences under the false veil of "security".


WHY DO I NEED A PASSWORD APP?

• Re-using a memorable password is like giving everyone your car keys.
• Inventing many good passwords is difficult; remembering them, almost impossible.
• "Clever" encoding schemes such as Tr0ub4dor&3 don’t work either: criminals know we do this and brute-force it with ease.


IS MASTER PASSWORD SAFE?

There is a lot more to safety than using "military grade encryption".

• Strong passwords: They are too expensive for hackers to reverse.
• Not saved: Thieves or officials confiscating your hardware will find no secrets on it.
• Ubiquitous: You can use ANY device to instantly calculate your site passwords.

• Save custom passwords: They are AES-encrypted and saved.
• Strong protections: Salting and key derivation keep your master password safe.
• Free Software: Source available and evaluated by independent experts. There is no fairy dust, only mathematical precision.


HOW DOES IT WORK?

Master Password is based on a cryptographic algorithm hardened against all forms of attacks, including brute-force, rainbow tables, length extension, cypher weaknesses, expensive computing power, etc.

In its essence, Master Password is based on:
ENCODE( HMAC-SHA256( SCRYPT( masterPassword, userName ), siteName | siteCounter ), siteTemplate )

This is a simplified representation. See http://masterpasswordapp.com/algorithm.html for more information.


TIPS:

‣ Don't reuse an old password as your new master password.
‣ Check out the App Store on your Mac or the homepage for the desktop version.
‣ A short sentence is a great master password! Quick to type and easily recalled, eg. banana colored duckling

A password app that I can run on my Windows laptop, my iPhone, my MacBook and NEVER HAVE TO SYNC UP. Even better, even if I’m away from all my devices, as long as I can reach the web, I can pull up the app, key in my passcode and site name and there’s my password for the site, service, or resource. And nothing laying around for hostiles to decrypt or reverse-engineer.


A novel and conceptually elegant approach

Why isn’t everyone using this approach? The app UI and finish also are beautifully crafted. Great work! Thanks


Love the app
MendelG

But I wish it let me import my list of websites from the desktop version, when I try I just get an error


Read mine.......??

Idk how to really actually use this M password thing but there’s a lot of good reviews that it works than bad reviews and the bad reviews don’t really make sense so I think this M password thing is useful even though I don’t know how to use it....


Amazing App

Una de las mejores App para manejar la seguridad de nuestras contraseñas!!!


The best
Jajajajajjasjnaa

This is by far the best password manager on the App Store. Does what others should.


Ingenious.

An excellent solution for your most sensitive passwords.


Passwords and Math
Brysonsd88

I was totally skeptical that this wasn’t just another password backup app but it uses math and algorithms to generate the passwords so as long as you know your key info like your full name, passphrase or password, and the website for the login you will NEVER LOSE YOUR PASSWORDS. That part makes me stoked to use this app on my phone and computer. Totally simple and streamlined. Encrypted and safe. Thanks you developers for making math work in an awesome way that keeps us safe from bad password habits.


Great
Infighting offhand

Great app


Very secure and easy to use

Definitely not for the faint of heart or someone that needs credentials synced between systems. For the paranoid or someone wanting a strong password manager, this is definitely the best option. There is no backup to the cloud, just remember a couple of details and passwords are generated on the moment.
