What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Use a long, unique passphrase that you can remember, and use it only to unlock your password manager. Turn on multifactor authentication (MFA) if the manager supports it, and protect its recovery options. The manager should create and fill a different password for every other account.
Choose a master password that is long, unique, and hard to guess
Your master password is the key to the password vault, so never reuse it for email, shopping, or any other account. If another service exposes a reused password, someone could try it against your manager.

NIST recommends at least 15 characters when you must create a password. A passphrase made from several words can be easier to remember while giving you room to make it long. Choose words and a combination that are not a familiar quotation, a common phrase, or connected to personal details such as your name, birthday, or pet. Do not use a passphrase example published in a guide: once public, it is no longer secret.

NIST’s current standard requires services that verify passwords to check proposed passwords against a blocklist of common, expected, or compromised choices. A long phrase can still be a poor choice if it is widely known or tied to you.

What NIST’s length rules mean
NIST SP 800-63B-4, published in July 2025, requires a centrally verified password to be at least 15 characters when it is used as a single authentication factor. If a password is used only as part of an MFA process, the verifier may allow a minimum of eight characters; that is a service requirement, not a good target for your master password. NIST recommends that verifiers permit passwords of at least 64 characters.
These are requirements and recommendations for services that verify passwords—not a guarantee that every website or password manager accepts every length or character. Check the manager’s actual input limits. The practical goal is a long, memorable, unique passphrase that fits the service.
Use a password manager for every other account
Use the manager to generate a distinct, hard-to-guess password for each account, then let it autofill credentials on the right site or app. This avoids the temptation to reuse your master password or rely on a small set of variations. NIST says verifiers must allow password managers and autofill; its implementation guidance explains that managers help people use unique passwords and can protect against guessing, cracking, and password-spraying attacks.

When choosing a manager, compare the features that affect your ability to use and recover the vault:
- MFA and passkeys: Check which additional sign-in factors the manager supports and whether they work with your devices.
- Recovery and emergency access: Understand what happens if you forget the master password or lose access to a device. Do not assume the provider can restore a vault; recovery capabilities vary.
- Encryption and storage: Read how the provider says vault data is encrypted and where it is stored.
- Devices and autofill: Confirm that it works on the platforms and browsers you actually use.
- Portability: Check whether you can export credentials or otherwise move them if you switch services.
These are questions to assess for a particular manager, not claims that every product has the same protections or recovery features.
Protect the manager login with MFA and safe recovery
Enable MFA for the manager if it is available. Depending on the service, a passkey or compatible hardware security key may be an option. A physical security key is an additional sign-in factor, not a replacement for the master password or a way to store the vault itself; check that the manager supports it before relying on one.
Read the manager’s recovery instructions while you still have access. If it provides recovery codes or other recovery material, keep them somewhere secure and separate from routine access to the vault. Avoid leaving the master password in an unprotected note, on a visible label, or alongside the device that opens the vault.

Skip arbitrary character rules and scheduled password changes
Modern NIST guidance does not recommend forcing people to combine uppercase and lowercase letters, numbers, and symbols just to meet composition rules. It also says verifiers must not require routine periodic password changes. A predictable suffix added to satisfy a rule is less useful than a long, unique passphrase; follow the manager’s actual input limits rather than inventing complexity for its own sake.
Change the master password when there is evidence it has been compromised, rather than on an arbitrary calendar. If you suspect the vault itself has been exposed, follow the manager’s incident guidance and rotate the affected account credentials. A manager’s specific response steps depend on its design and instructions.

Remember what a strong password cannot do
Passwords are not phishing-resistant, as NIST states. A long master password cannot by itself prevent phishing, malware on a device, or compromise of the vault or service. MFA adds a separate factor, and passkeys can offer a more phishing-resistant sign-in option where supported. Keep your devices and recovery paths protected as well as the password.
NIST’s consumer guidance recommends using a password manager for accounts that require passwords. The manager handles the many unique credentials; your job is to make its master password distinctive, memorable, and protected.
