Answer:
Add a number to make the password strong and a capital letter
Step-by-step explanation:
It is a good idea that the user is trying to remember the password but using the same word every month and changing only a letter makes it a 'weak password' and it can be easily copied and guessed by someone who may have been observing him.
Such a person can log into his system after a series of trials hence in order to make password's strong it is advised that it should be alphanumeric
hence the user should try and add numbers or at least a number to the password and also a capital letter
