Passwords are usually a combination of numbers, letters and special symbols that serve as access keys to devices (eg computers, smartphones), computer programs or even online services such as email, social media and other platforms with confidential data. Password security is often underestimated, serving to protect your digital identity. Use different passwords for each account. If these are more passwords than you can remember, use a password manager. With a master password, all other passwords are managed here. Also choose a secure password. This should contain uppercase and lowercase letters as well as at least one number and one special character and in total, it should contain at least 8 characters.
