Argon2 is a tool that we use to make our passwords super safe. It’s like a special secret code that only you know, and it keeps your online accounts and personal information safe from hackers.
When you create a new password, Argon2 takes your password and mixes it up with lots of other numbers and letters. It then scrambles them in a special way so that nobody can read them or guess your real password. This makes it very hard for a hacker to figure out what your password is.
Argon2 also makes passwords really hard to crack by making it take a very long time for a hacker to guess it. So even if a hacker is very smart and knows a lot about you, it would take them a very long time to guess your password using a method called "brute force".
Argon2 is really important because it helps protect all the things that you care about online, like your email, your social media, and your bank account. So always make sure to use a good password that is hard for people to guess, and never share it with anyone!
