Security experts generally recommend that you use strong, unique passwords for each of your online services and accounts.
Strong passwords that contain several different types of characters are compulsory for some online services – the password that you enter when you sign up is not accepted if it is too short or not complex enough.
However, even if you come up with a highly complex password that is virtually impossible for anyone else to guess, the safety of your account to online services is at risk if you use that same password for each account. For example, if hackers gain access to the login details for one of the services that you use, they can then use that information to access any of your other online accounts where you have used the same password. Using a unique password for each account means that even in the event of a data breach in one of the services you use, your other accounts are not at risk.
Tip: While you can still renew your F-Secure KEY subscription, we strongly urge you to try F-Secure ID PROTECTION. It is the same great password manager, but also includes online identity monitoring to help you prevent identity theft. See how to move from KEY to ID PROTECTION.
