What is a password manager?

A password manager does the work of creating, remembering, and filling in passwords for you. Save a password once and LastPass will autofill it the next time you need to log in.


Benefits of using a password manager

How does a password manager work?

Password encryption and storage 

Password managers protect your passwords by storing them for you. With LastPass, you receive an encrypted password vault to store your passwords, login credentials, payment info, addresses, and secure notes in.

A LastPass password vault is secured by zero-knowledge encryption, which ensures your data remains visible only to you. Your master password is the only key which can unencrypt your password vault.

Save and autofill functionality

Save a password to your LastPass password vault, via web browser or mobile apps, and it’ll auto-sync across all your trusted devices. The next time you need to log in, LastPass will autofill your login credentials for you. Save and autofill also works for addresses and payment info to streamline online checkout.

Built-in password generator

Avoid password vulnerabilities, like the reuse of weak passwords, with the LastPass password generator. It’ll generate complex passwords for all your new accounts so you can improve your password security practices.


What can I do with a password manager?

Store sensitive personal documents

LastPass lets you create secure notes inside your password vault, where you can store your sensitive information and documentation, like additional copies of your passport, license, credit cards, WiFi passwords, and more.

Protect your banking information

Login information for banking providers are a common target for hackers, as the information is the most valuable to them. Avoid vulnerabilities by storing your banking login credentials in a password manager, where they’ll be protected by top-of-the-line encryption methods.

Securely share credentials

Protect your password security with LastPass’ end-to-end encrypted sharing, which allows you to safely share sensitive information with family or team members.

What makes a password manager a secure solution?

Master password and encryption key

As mentioned above, your master password is the only key which can unlock your LastPass password vault. Think of it as your unique security key: due to its encryption, only you will ever know what your plaintext master password is – not even LastPass knows it.  

Two-factor authentication (2FA)

2FA increases cybersecurity by requiring additional authentication, on top of your master password, to unlock your password vault. Two-factor authentication methods include: biometric authentication, like a fingerprint scan, SMS codes, one-time passcodes, and push notifications for iOS and Android to the LastPass Authenticator app.

Dark web monitoring and password security score

Dark web monitoring helps you avoid cybersecurity vulnerabilities by notifying you whenever an email address or login credentials are compromised online. Similarly, your up-to-date password security score monitors your cybersecurity practices, identifying instances of weak passwords and reuse, which you can address via unique passwords.

Get started with LastPass password manager


Sign up for free trial

Whether you’re a single user, family, small team, or business, you can sign up for a free trial of LastPass – no credit card required.


Create your master password

Once signed up, you must create the master password for your password vault. Make it unique yet memorable – something only you’ll know.


Download extension or app

Download LastPass on the devices you’ll most be using it on, from web browsers to mobile apps, to experience LastPass while you’re on the go.


Save or import passwords

Begin adding your existing passwords to LastPass. You can either save them as you log in to sites and apps or import them from other password managers.

Challenges of using a password manager

Initial setup and learning curve

Getting started with a new app can be stress-inducing, but LastPass makes password management as easy as possible. With LastPass, it’s as simple as signing up, downloading the LastPass browser extension or mobile app, logging in, and start saving your passwords. Save a password once and we’ll autofill it the next time you need it.

Dependency on a single master password

A single master password may sound like too little security for a password manager app, but it’s the essential key to protecting your account. That’s why it’s important to create a memorable, unique password only you will remember: one, so hackers will never be able to guess it, and two, so you’ll never forget it.

Best of all, once you’ve input your master password to verify one of your devices, you can establish passwordless login. This will allow you to log in, in all future instances, using the LastPass Authenticator app, your fingerprint, or a hardware key. While you’ll need to remember your master password, you can feel good about not typing it every time you access your LastPass vault.

Potential risks of cloud-based storage

Some worry that cloud-based storage could put your online accounts at risk of hackers. But the truth is that your data is secured within the cloud. The LastPass zero-knowledge encryption model, with hashing and salting, protects your LastPass password vault and data by never storing it in its plaintext form. Rather, it’s saved as unintelligible, scrambled gibberish which can only be unencrypted on your devices.

Types of password managers

Cloud-based password managers

Cloud-based apps are password managers which store your passwords in encrypted cloud servers. Your passwords are accessible only on your trusted devices, which are the only devices which can access and verifiably unencrypt your data from the cloud. These include LastPass, 1Password, Nordpass, Dashlane, and others.

Local password managers

Local password managers, like Enpass and KeePass, store your passwords locally to your device. Unlike a cloud-based password manager, your data does not sync across multiple devices with a local password manager: your passwords are only available on the device they’re saved on.

Browser-integrated password managers

Browser password managers are password managers that are built into the browser itself, like Safari, Chrome, Edge, and Firefox. While convenient, they’re not as secure as other types of password managers due to their lack of high-end security protocols.

Best practices for password management

Creating strong and unique passwords

You should create a strong password every time you make a new account. It’s one of the simplest ways to secure your account, as weak passwords are the easiest entry point for hackers. To create a unique password, use the built-in LastPass password generator.

Regularly updating and changing passwords

It’s a good idea to update your passwords every so often. Making it a habit protects against compromised accounts and potential data breach risks. It’s also smart to do when you first create your password manager account, as you may realize you’ve been using reused and weak passwords.

Enabling multi-factor authentication

Multifactor authentication adds an additional layer of security to your LastPass password vault by putting another layer of authentication on top of your master password. Whether it’s a push notification to your phone, a one-time password, or a fingerprint verification, it’s a simple way to protect your sensitive information, as you’ll be the only person who can authenticate your identity and unlock your password vault.

“I like that LastPass is easy to use and intuitive. It integrates well with all websites and allows me to keep secure encryption for all my personal and work-related accounts. It allows me to organize folders, share with others, and only memorizing one master password for all of those while keeping encryption secure is a relief.”


Kenny Kolijn

Independant business coach

“I use LastPass both corporately and personally. It allows me to securely store and share passwords with my family and co-workers in separate environments and happily generates random secure passwords for me, which prevents me from re-using the same one.”


Erik Eckert

System administrator, MPE Engineering Ltd.

“If you deal with other people's information, as my company does, LastPass is a must. We use it to organize sensitive client credentials, which has never failed us. Its level of security offers us flexibility if we have a vendor or team member that needs access but don't want to share the actual password.”
