Then use a unique password for every account and turn on multi-factor authentication (MFA) wherever it is available. A password manager can make unique passwords easier to create and keep, but the vault itself also needs protection.
What to do first after a password breach
- Check what was exposed. Read the breach notice and follow its directions. The Federal Trade Commission (FTC) advises changing the password implicated in a breach and any similar password used elsewhere. FTC guidance on responding to a data breach.
- Change affected and reused passwords. Start with the breached service, then update other accounts where you used the same or a similar password. Give each account a distinct password.
- Use a password manager if it helps you keep passwords unique. The FTC recommends considering one to create complex, unique passwords without memorizing them. FTC advice on protecting personal information.
- Enable MFA. Turn it on for the affected account and other important accounts where available. The FTC says an additional authentication factor can help secure an account even if its password is exposed. Follow the breach notice’s advice for any other information involved; the FTC directs affected people to IdentityTheft.gov/databreach for identity-theft steps.
What to compare in a password manager
The evidence here supports criteria for evaluating a manager, not a ranking of current products. Check the service’s current documentation before choosing; no particular vendor can be identified as the most secure on this basis.

| What to check | Why it matters | What to verify |
|---|---|---|
| Vault access protection | A vault stores many credentials together, so access to it deserves special attention. | Whether MFA is supported and which security controls you can enable. CISA advises securing and limiting access to password managers and enabling available security features. CISA password guidance. |
| Encryption and device access | Putting credentials together creates a concentration risk: one compromised vault could expose many accounts. | CISA’s technical guidance identifies encryption at rest and device-based or cached vaults as possible mitigating controls. Treat these as questions to investigate, not proof that a particular service implements them well or that one architecture is always safest. CISA technical guidance on MFA and password managers. |
| Unique-password workflow | The practical benefit after a breach is avoiding reuse, which can let an exposed credential put other accounts at risk. | Whether the manager makes it straightforward to create and keep distinct passwords for different accounts. The FTC recommends using a manager to help create unique passwords. |
| MFA options for your accounts | MFA is separate from password storage: a manager does not itself turn on a second factor for the accounts in its vault. | Check the supported MFA methods on each important account. Authentication apps and physical security keys are among the possible methods, but compatibility varies by account. CISA describes MFA as a layered protection; its “More than a Password” page is archived. CISA MFA overview. |
How to protect the manager’s vault
Because the vault concentrates credentials, secure access to it deliberately. Review the manager’s security settings and enable the protections it offers, including MFA if supported. CISA identifies physical security keys as one possible MFA method, but whether a key works depends on the specific service and account. Do not assume that selecting a password manager automatically protects the accounts stored in it: enable MFA separately on those accounts where available.
What a password manager can—and cannot—do
A manager can make it easier to keep account passwords distinct rather than reusing credentials. It does not undo a breach, replace changing an exposed password, or guarantee protection against every way an account can be compromised. MFA adds a separate layer, and the breach notice may call for other steps if information besides a password was exposed.

What this evidence does not establish
The available sources do not compare current password-manager vendors, their independent audits, recovery designs, platform compatibility, or prices. They support a practical selection checklist, but not a claim that one named service is the best or most secure. Verify a candidate’s current features directly before relying on them.
