Is your feature request related to a problem? Please describe.
Changing passwords periodically would add another layer of security. This can be opted out by the user.
Describe the solution you'd like
send a reminder to change passwords every 3 months. This can be easily implemented by storing the date on which the program was first used and then letting the user know it's time to change 3 months after that date has passed.
Describe alternatives you've considered
Haven't considered any other alternatives.
