Password management software is important because it helps you create strong, unique passwords for all of your online accounts, and stores them in a secure, encrypted manner. This is important for several reasons:

Strong passwords are more difficult to guess or crack, which makes it harder for hackers to gain access to your accounts.

Unique passwords help to prevent one compromised password from being used to gain access to multiple accounts. If you use the same password for multiple accounts and one of those accounts is compromised, the hacker could potentially gain access to all of your accounts.

Encrypting your passwords makes it harder for someone to steal them. Even if a hacker does manage to get hold of your password manager’s database, they will not be able to read the passwords without the proper decryption key.

Using a password manager also makes it easier to use strong, unique passwords, as you don’t have to remember them all yourself. This can be especially helpful if you have a large number of online accounts.
