As a good practice I always state that passwords should never be reused (or similar) but in Password Manager Pro it is only possible to configure the password policy option "Password should not be same as last" from 1 to 10 (This is also for the "Password should not be very similar to last" setting.).
I can understand that Password Manager Pro doesn't support the option 'Never' but is 10 in this situation enough?
Different industry standards have different recommendations for this and systems also support different settings (like Microsoft AD (On prem) supports 0-24).
