Users should change passwords for internet services after 90 days at the latest. This is what experts of the “Germany Safe on the Net” (DsiN) association recommend.
This helps to protect users from data theft from the servers of internet services, which is otherwise hard to prevent.
Recently, over 170 million user name and password records from the career network LinkedIn have surfaced, which the company says date back to a hacker attack in 2012.
Many programs or services will automatically send out reminders when a password has been used for too long.
You shouldn’t ignore these requests, but make the necessary changes immediately to avoid forgetting or postponing it, advises Germany’s Information Security Agency (BSI).
If you only receive reminders from some of your programs and services, or none at all, you can set up a repeat alarm in your smartphone calendar. -DPA
