Is it possible to set certain requirements on passwords?

Yes, this is possible. The admin can adjust this by going to 'Settings' > 'Shop' > 'Passwords'.

Here you can set rules for:

• Minimum password length users (default 4 characters)
• Minimum password length admins (default 4 characters)
• Minimum quantity of capital letters
• Minimum quantity of numbers
• Minimum quantity of punctuation marks
• Set a check on 3 or more of the same characters consecutively
• How long is a password valid (in months)
• How many passwords in the past do we need to check before creating a new one?
