Passwords, on many occasions, are the only thing that separates our information from the hands of others.
All -or the vast majority- of the accounts we manage on the Internet have one thing in common: they ask us for a user and a password to access. We have always used those two values to identify ourselves in the service, such as key of a particular house which we enter from time to time.
The problem is that many times we use an insecure key to save all that information, or we use the same key to open all the doors. In those cases it is too easy to find out what that key is, or to find out once – through a leak, for example – you gain access to all accounts. A problem that password managers are trying to solve, but how do they want to do it?
What is a password manager for?
A password manager is a program that is responsible for collecting the passwords for our accounts, leaving them in a safe place and offering functions such as entering them by us or changing them automatically. In other words, it serves to keep our passwords in one place securely.
How do they work?
Typically password managers use a master password to allow us to see the data they store, which in some cases we can combine with other security measures such as using a fingerprint or two-step verification.
Once we have access, we can access the passwords that we have stored, and usually have the same password manager enter them every time we need them. That way we don’t have to remember passwords by heart, nor do we have to enter them by hand on the page when asked.
Why are they necessary?
When creating passwords, there are two rules to followWithout exceptions:
- Use strong passwords (long length, with digits and symbols)
- Do not repeat passwords between services
We can create strong passwords and remember them; the problem is not repeating those passwords when we have more than 50 user accounts -for example-. A password manager can help us create strong passwords, and not repeat passwords between services by keeping track of all the ones we use.
What options are there?
exist many options of password managers; here we quote several, although we do not analyze them and we will probably leave some in the pipeline. You can tell us which managers you use and your experiences in the comments.
