Generating really good strong passwords can often be difficult to do consistently for different websites. The handy utility called “pwgen” in Linux Mint/Ubuntu makes this process very easy.
1. Open Terminal and type :
sudo apt-get install pwgen
2. Once installed, to start generating random passwords, simply type pwgen and select any of the passwords that are displayed.
3. To really generate strong random passwords, use the -s option :
pwgen -s
Finally, there are other options too that can be tried out like generating only numerical/non-numerical passwords, havinging at least a capital letter or a wild card character and so on. Make sure to check out the syntax for those using the man page for pwgen by typing :
man pwgen
Cheers.
