Make passwords looooooong ...
The longer it is, the harder it is for a hacker to crack. It takes less than one second to crack a three character password.
A good rule of thumb to follow for password security: anything 16 characters or more is considered to be a strong password.
Don't use "password123!"
Your passwords need to be hard to guess. Steer clear of sequential or repetitious patterns and avoid using any obvious personal information when creating a password.
Be sure to include numbers and special symbols, as well as both uppercase and lowercase letters.
Do NOT reuse passwords. EVER
Be sure to change your passwords on a regular basis to help keep your information fresh and reduce the chances of one of your passwords becoming exposed.
Use a password manager
Keeper is a good choice for a cross-platform password manager. If you opt not to use one, at the very least, take pen to paper and keep a detailed record of all your login credentials and passwords.
You should never feel like you have to memorize every single one of your passwords. While some people only have a handful of passwords to keep track of, it’s quite simple to accumulate dozens of passwords when you consider all of the social media, bank accounts, streaming, and apps that an individual may have.
Don't share your passwords
verify passwords monthly!
Set a reminder to check your passwords monthly. This helps ensure that none of them have been compromised or stolen without your knowledge.
It’s almost impossible to stop your passwords from leaking out and gaining unwanted exposure, whether it’s through a malicious hack or an unfortunate data breach. However, there are online resources, such as Google’s Password Manager and haveibeenpwned, that allow users to check their current passwords against a database of known password compromises.
An even simpler option is to use a password manager like Tip 4 suggests. Most management software has a built-in feature to run the checks against all your passwords at once, making the task way simpler.
