Most people have more online accounts than they can realistically keep track of. Email, banking, shopping, social media, school, work, and streaming services can all require different passwords. Trying to remember every password can quickly become frustrating, which is why many people turn to password managers.
A password manager is a tool that stores login information in an encrypted vault. Instead of remembering dozens of different passwords, you generally only need to remember one main password to access the vault. From there, the password manager can fill in your login details when you visit a website or app.
Why Passwords Can Be Difficult to Manage
Using the same password for multiple accounts might seem convenient, but it can create a serious security problem. If one website suffers a data breach and your password is exposed, someone could potentially try that same password on your other accounts.
Using a different password for every account is much safer, but it creates another problem: remembering them all. Password managers are designed to solve this problem by keeping those passwords in one protected place.
They can also generate random passwords that are much harder to guess. Instead of creating a password based on a name, birthday, or familiar phrase, a password manager can create something long and unpredictable.
How a Password Manager Stores Your Information
When you save a password in a password manager, it isn’t supposed to simply sit in the system as readable text. Reputable password managers use encryption to protect information stored in the vault.
Encryption changes readable information into a form that cannot easily be understood without the appropriate key. When you unlock your vault, the password manager can decrypt the information so that you can use your saved passwords.
Many password managers are designed around a system where the provider does not have access to your master password. This can reduce the amount of information the company itself can access, although the exact design varies between services.
This is one reason your master password is particularly important. If the password manager uses a zero-knowledge or similar architecture, losing your master password may mean that the provider cannot simply retrieve it for you.
What Happens When You Log In
A password manager can make logging into an account fairly simple.
For example, you might visit an online store where you already have an account. The password manager recognizes the website and offers to fill in your username and password. After confirming the information, you can sign in without manually typing the password.
Some password managers can also fill in addresses, payment information, and other details. This can save time, although users should still be careful about where they allow sensitive information to be entered.
Generating Strong Passwords
One of the most useful features of password managers is automatic password generation.
Instead of coming up with something like a familiar word followed by a few numbers, a password manager can generate a random combination of letters, numbers, and symbols. It can also create longer passphrases when a website allows them.
The important part is that the password does not need to be memorable when the password manager is storing it for you.
Using a different strong password for each account also limits the damage from a single compromised password. If one password is exposed, it doesn’t automatically give someone the password to every other account.
Protecting the Password Manager Itself
A password manager can protect many of your accounts, but it also becomes an important account to protect.
Your master password should be strong and unique. It should not be the same password you use for your email, social media, or other accounts.
It is also worth enabling multi-factor authentication if the password manager supports it. This adds another layer of protection by requiring something beyond your password when signing in.
Users should also keep their devices and password manager applications updated. Security updates can fix vulnerabilities and improve the way the software protects stored information.
Are Password Managers Completely Safe?
No security tool can guarantee that an account or device will never be compromised.
Password managers can still have vulnerabilities, and a user’s device could be infected with malicious software or accessed by someone else. There are also risks associated with phishing, stolen credentials, and weak master passwords.
The goal of a password manager is not to make someone completely immune to these threats. Instead, it can make good password habits much easier to maintain.
For example, rather than reusing one password across ten websites, a password manager makes it practical to use ten different passwords without having to memorize all of them.
Why Password Managers Can Be Useful
The biggest advantage may be the combination of security and convenience. Strong security practices are easier to follow when they do not require a lot of extra effort.
A password manager can help users:
- Create unique passwords for different accounts
- Generate long and difficult-to-guess passwords
- Store passwords in an encrypted vault
- Automatically fill in login information
- Find and update old passwords
- Reduce the temptation to reuse passwords
- Keep other sensitive information organized
These features can be especially useful for people who have accumulated dozens of online accounts over the years.
The Human Side of Password Security
Technology can only do so much. A password manager cannot protect an account if someone willingly gives their password to a scammer, approves a suspicious login, or leaves their unlocked device unattended.
Phishing is a particularly important concern. A fake website can look almost identical to a legitimate login page and attempt to convince someone to enter their credentials.
Some password managers can help with this by recognizing the website they are supposed to fill information into. However, users should still check website addresses and be cautious about unexpected login requests.
Choosing a Password Manager
There are many password managers available, and they do not all work in exactly the same way. Before choosing one, users may want to look at how the service handles encryption, account recovery, multi-factor authentication, device support, and security audits.
It is also worth considering whether the service works across the devices and browsers you regularly use. A password manager is most useful when it fits naturally into your everyday routine.
Most importantly, users should understand how the service handles their data and what happens if they lose access to their account.
A Simpler Way to Handle Online Passwords
Managing passwords manually becomes harder as the number of online accounts grows. Password managers offer a practical way to handle this problem by combining encrypted storage, password generation, and automatic login features.
They are not a replacement for good security habits, but they can make those habits much easier to maintain. Using unique passwords, enabling multi-factor authentication, keeping devices updated, and staying alert to phishing attempts can all work together to make online accounts harder to compromise.
For someone managing dozens of accounts, the biggest benefit of a password manager may simply be that strong password security becomes much less difficult to keep up with.
