Updating your devices, whether it is your computer, smartphone, or any other smart devices, is recommended in order for the devices to receive critical security updates. The more out of date your device is, the more insecure it becomes, making it easier for someone to hack into those devices. Keeping devices up to date is one of the best ways to ensure that you keep your information safe.
Other important things to do to keep your information secure:
Secure Passwords: First, make sure that you are not using the same password for multiple accounts simultaneously. An important thing is to also create a long password with both capital and lowercase letters, as well as multiple symbols. Furthermore, it is recommended to make the password a phrase. Phrases are easier to remember and harder to crack.
Two-Factor Authentication: Two-factor authentication, on top of having secure passwords, makes it even harder for someone to hack into the account. Examples of two-factor authentication include sending a code to an email, sending a code via text, or a prompt on a device alerting of a sign-in attempt. You can enable one or multiple of these for an account. The more you enable, the safer the account will be.
Password Managers: It can be hard to remember all the passwords for all the accounts you have, especially if it is recommended for you to not reuse a password. One way to help with that is to store all your passwords on a password manager that requires its own secure password. The advantage of this is that you would only need to remember one password instead of multiple different passwords.
