The internet and apps have their benefits, but they also come with hidden dangers. There's no need to be too scared, but the more things seem to be okay, the more important it is to have the ability to stop and think.
Tell children that if they know one password, they can chain it to other places and get in trouble.
If one thing is found out, it won't end with just one thing.
If you use the same password for multiple services, if your password is found on one of the services, it's more likely that you'll be able to try it on the others. The idea that "this is all you need is fine" will spread.
It becomes easier to protect by just separating
You need to find ways to make it easier to remember everything, but just not reusing the same things over and over again makes a big difference. The more important your account is, the more worth keeping it separate.
Remember the passwords you use and check if you are using the same one again.
At Digital Kodomo BASE, we value being able to discern and choose rather than being afraid. Safety is not something you have to endure, but rather a power that you can use effectively over a long period of time.
