Lost password, option 3 didn't work, but I have backup
is it possible to convert the password as listed in the backup config file into the original password?
The config contains the hashed password (that also ends up in the FreeBSD passwd file). It is generated from the real password by crypt() : http://php.net/manual/en/function.crypt.php
As that says:
Note: There is no decrypt function, since crypt() uses a one-way algorithm.
So pfSense and FreeBSD can verify the password you enter, but can't (easily) reverse it.
I guess you could use some brute-force cracker to run against the hash value that you have.
But I wonder why console menu option 3 did not work?
doing a search, I saw another instance where 3 didn't work and they speculated it had reached some max and converted to read only…. IDK
