Mnemosyne generates passwords from a passphrase of your choice and a user name. Generated passwords are never stored to the device, they are recreated from the passphrase that you memorize and the user name.
Mnemosyne runs on iPhones and iPads and supports iOS 9 multitasking enhancements like Split View and Slide Over.
An administrator has to manage the user accounts on several Mac's in his company. He is required to use strong passwords but he is not allowed to store the passwords to disk or to write them down. This is where Mnemosyne comes in handy.
The admin chooses a passphrase that he will always memorize (for example "my iphone rocks"). With a length set to 8 and a strength set to "0-9,a-Z" the generated password for the user "sue" is "ueUQggIc". Using the same settings (and the same passphrase!) the password for the user "john" is "OOgIug2q". You can try it for yourself: enter "my iphone rocks" into the "Pass Phrase" field, "sue" into the "User" field and set length to 8 and the strength to "0-9,a-Z". You should get "ueUQggIc" as the password.
Whenever the admin needs to login into Sue's or John's account, he will enter his secret passphrase "my iphone rocks", the user name ("sue" or "john") and the "Length" and "Strength" values "8" and "0-9,a-Z" into Mnemosyne to reconstruct the password.
So all you have to remember is the passphrase. And of course make sure not to share the passphrase to anyone!
The app does now also support the “0-9” mode as currently implemented on some other platforms (Settings -> Use legacy "0-9" Mode).
Ratings and Reviews
Like hashapass, but better
I like the fact that you can control the length and what characters are used in the password generation. It would be nice of the dev would add the option for longer passwords and perhaps which special characters are used. But other than that it's great and having the ability to install it on windows or Mac is another added bonus (portable app would be better, so you can run it from a flash disk).
Very easy to use! Creates strong passwords of different lengths using a seed password and the account name (email, website, file name, etc.). I have been using this app on my phone for over a year and it works great. I also use the desktop version on my PC.
Great app for passwords
Perfect app. Exactly what I was looking for. Only suggestion would be to change the font used for generated passwords. The capital O and 0 look very similar. Also, the Special+ should use only common accepted password chars.
With Family Sharing set up, up to six family members can use this app.
