If your passwords are written on sticky notes, a password manager can help you switch to long, unique passwords without trying to memorize them all. Start by choosing a manager that fits your devices, protect its vault, then replace old passwords as you use each account. You do not have to move every login in one sitting.
Why move passwords out of sticky notes?
Every account should have a different, hard-to-guess password, but remembering many of them is difficult. A password manager can generate and store those passwords so you only need to remember the password that opens the vault. The Cybersecurity and Infrastructure Security Agency (CISA) cautions that physical or digital notes kept in plaintext can be exposed if someone gains access to the device or place where they are kept. That does not mean every paper note is equally at risk; it is a reason to avoid relying on an exposed list as your password system.
A manager is not a complete shield: it cannot by itself prevent phishing, a compromised device, or every kind of account takeover. Pair it with multifactor authentication (MFA) where available and keep your account-recovery options in mind. CISA’s password-manager guidance explains the role of managers and the factors to weigh when choosing one.
Step 1: Choose a manager that fits your devices and habits
Before saving passwords, check that the manager works on the computer, phone, tablet, and browsers you actually use. Compare how it stores and syncs your vault, how you would regain access if locked out, and what MFA and password-generation options it offers. CISA advises considering both the product and its developer rather than choosing on convenience alone.
Cloud sync or local storage?
Cloud storage can make a vault easier to use across devices, but it means vault data is stored on a service provider’s server. A locally stored vault can reduce that dependence, but you are responsible for keeping dependable backups and maintaining access across devices. Neither approach is automatically best for everyone: choose the trade-off you can manage safely.

Check compatibility, recovery, and reputation
- Confirm support for each device and browser you use.
- Understand how account recovery works before you rely on the vault. Recovery arrangements differ, so make sure you know what happens if you forget the vault password or lose access to a device.
- Check that the generator can create long, random, unique passwords.
- Review available MFA methods and assess the provider’s reputation.
CISA’s December 18, 2024 Mobile Communications Best Practice names examples in the password-manager category, including Apple Passwords, LastPass, 1Password, Google Password Manager, Dashlane, Keeper, and Proton Pass. Those examples are not a ranking or endorsement; check each product’s current features and compatibility before choosing.
Step 2: Set up and protect the vault
Create a strong, unique vault password—also called a master password in some products. It protects access to the credentials you store, so do not reuse a password from another account. CISA recommends protecting the vault with a long, unique, random passphrase. Decide how you will handle recovery before depending on the manager, and follow its own instructions for storing or recovering access.

Turn on MFA for the password manager if it supports it. MFA requires another proof of identity in addition to your password. The Federal Trade Commission (FTC) explains that a second factor can help stop someone who has obtained your password but does not have that other factor. Depending on the service, options may include an authenticator app or a compatible security key. A hardware key is optional, and compatibility varies; check the manager’s supported methods before buying or setting one up. See the FTC’s two-factor authentication guidance.

Vault MFA and website MFA are separate protections. If a bank or email service offers MFA, enable it on that account too; securing the vault does not automatically secure every login stored inside it.

- Requires 3 "AAA" batteries (included)
- Unit auto-locks for 30 minutes after 5 consecutive incorrect PINs
Step 3: Replace old passwords as you log in
Install the manager on the devices you use, then migrate gradually. When you next sign in to an account, replace its old password with a generated, unique one and save the new login in the vault. This practical, account-by-account approach avoids turning setup into a large one-time project.
- Start with your email account. Password-reset links for other services often go to email, so the FTC says it deserves particular attention.
- Move on to other important accounts. Prioritize accounts that could expose sensitive information or help someone reach your other accounts, such as financial services.
- Update remaining logins over time. Use the manager’s generator for each account rather than reusing one new password in several places.
The FTC recommends strong, unique passwords, and CISA recommends password managers to create and remember them. The FTC’s password guidance also explains why unique passwords matter. You do not need to change every password on an arbitrary schedule. If a service reports that an account was compromised, change that password promptly; if you reused it elsewhere, change those copies too.

A password manager shifts the task from remembering a collection of passwords to protecting one vault and using a different generated password for each account. It can make unique passwords practical, but it does not replace MFA, careful recovery planning, or caution around suspicious login requests. Keep the vault password unique, secure the manager and your important accounts with MFA where available, and continue to watch for phishing or device-security problems.
