Passwords are now saved in a password manager.

Browse source 
The password manager uses strong encryption using a key derived from the passphrase using
scrypt key strengthening algorithm. This ensures encryption is performed using a strong key
and that brute forcing the passphrase is time consuming.

If the user loses his passphrase no recovery is possible.

Password strength calculation:
seperate characters in couple of groups
For the use of characters from each group a certain value is added to the base value
which is meant to signify the size of the set of characters the password is based on.
Some analysis of relative positions might be required! Predictable placement of special charachters and uppercase/lowercase or numbers
should be penalized.
These calculations should result in a search space size per character
the base to the power of the length of the password gives the resulting strength
from this result we take the 10 log to get the magnitude of the value.
