Use strong and unique passwords
Passwords are the first line of defense against hackers trying to gain access to your accounts. Here are some essential tips for creating strong and unique passwords:
Avoid using obvious passwords
Using easily guessable passwords such as “password” or “123456” puts your accounts at great risk. Hackers often use automated tools that can quickly crack weak passwords. Avoid using common words, significant dates, or repeated characters as passwords.
Create long and complex passwords
The longer and more complex your password is, the harder it becomes for hackers to crack. Ideally, a strong password should contain a combination of uppercase and lowercase letters, numbers, and special characters. Aim for a password length of at least 12 characters for optimal security.
Use a password manager
Remembering multiple complex passwords can be overwhelming, which often leads people to reuse passwords or write them down. Using a password manager can help you generate and securely store strong passwords for all your accounts. With a password manager, you only need to remember a single master password to access all your other passwords.
