Use a unique, password-manager-generated password for your bank, turn on the strongest multifactor authentication (MFA) the bank supports, and secure the email account and password manager that help you recover access. These steps reduce reliance on a password alone, but available options vary by bank, account, device, and location.
What to secure—and why
A reused password can put a bank account at risk if another service where you used it is compromised. A password manager can generate and store a different, long password for each account, so you do not have to memorize or reuse them. The National Institute of Standards and Technology (NIST) recommends password managers for accounts that require passwords in its password guidance.

MFA adds another sign-in check beyond the password. It is an additional layer, not a guarantee against fraud or account takeover. The Cybersecurity and Infrastructure Security Agency (CISA) explains that passwords alone are no longer enough in its guidance on strong passwords. Your bank may offer different MFA options for account sign-in and for particular transactions.

Pick a manager that works on your devices and supports MFA for access to its vault. Before storing your bank credentials, understand how the manager stores or syncs data and how you would recover the vault if you lose a device or forget its sign-in details. CISA outlines tradeoffs between cloud-based and locally maintained password databases in its password-manager guidance.
#1 Best Overall
- POWERFUL SECURITY KEY: The Security Key C NFC is the essential physical passkey for protecting your digital life from phishing attacks. It ensures only you can access your accounts.
- WORKS WITH 1000+ ACCOUNTS: Compatible with Google, Microsoft, and Apple. A single Security Key C NFC secures 100 of your favorite accounts, including email, password managers, and more.
- FAST & CONVENIENT LOGIN: Plug in your Security Key C NFC via USB-C and tap it, or tap it against your phone (NFC) to authenticate. No batteries, no internet connection, and no extra fees required.
- TRUSTED PASSKEY TECHNOLOGY: Uses the latest passkey standards (FIDO2/WebAuthn & FIDO U2F) but does not support One-Time Passwords. For complex needs, check out the YubiKey 5 Series.
- BUILT TO LAST: Made from tough, waterproof, and crush-resistant materials. Manufactured in Sweden and programmed in the USA with the highest security standards.
- Use a strong, unique sign-in password for the manager and enable its MFA.
- Review the manager’s recovery process before relying on it as the only place your credentials are stored.
- Do not keep your bank password in an easily accessible plain-text file.
Set a unique password for the bank
- Open the bank’s official app or type its known web address yourself. Do not follow login links in unexpected texts or emails.
- Go to the bank’s security settings and change any weak or reused password.
- Generate a unique password with your password manager and save it in the vault.
NIST’s consumer guidance says, “For accounts that require passwords, NIST experts highly recommend that you use a password manager.” See NIST’s password guidance for its recommendations.
Turn on the strongest MFA your bank offers
Use the most phishing-resistant option available for your bank account, provided you also have a workable recovery route. CISA’s general ordering favors security keys over authenticator apps, and authenticator apps over SMS or email codes. NIST also explains that MFA methods differ in security and that text codes have vulnerabilities. The following describes typical relative strengths, not a promise that your bank offers every method:
Rank #2
- Requires 3 "AAA" batteries (included)
- Unit auto-locks for 30 minutes after 5 consecutive incorrect PINs
| Method | What to know | What to do |
|---|---|---|
| FIDO/WebAuthn security key or supported passkey | Phishing-resistant options; security keys are the strongest method in CISA’s listed ordering. Availability depends on the bank. | Use one if the bank supports it, and keep a recovery method available. Check the bank’s current security settings. |
| Authenticator app with number matching | A stronger fallback than basic push prompts where the bank supports it. | Match the number shown at sign-in and reject prompts you did not initiate. |
| Authenticator app with time-based code | Useful where supported, though a code can still be phished. | Enter it only on the genuine bank site or app that you opened independently. |
| Text or email code | Better than password-only access, but weaker and more exposed to interception or account takeover. | Use it if stronger choices are unavailable, and ask the bank whether it offers an alternative. |
CISA’s MFA guidance ranks common methods, while NIST’s MFA overview discusses phishing-resistant authentication and the limitations of text codes. Neither source establishes which methods a particular financial institution supports.

Secure the email and recovery routes
Your email account may receive password-reset links, so secure it with a unique password and MFA too. The Federal Trade Commission (FTC) warns, “If a hacker takes over your email account, they can get password reset links for your other accounts.” Read its account-protection advice.
- Save any bank backup or recovery codes according to the bank’s instructions.
- Protect the email account used for bank recovery with its own unique password and MFA.
- Keep the password manager’s recovery process in mind so a lost or unavailable device does not leave you without access to the vault.
Use alerts and review account activity
Authentication is one layer of account protection. Turn on the login or transaction alerts your bank provides, and review account activity through the official app or website. Financial-sector guidance discusses risk-based authentication and transaction controls as parts of managing access risk; the consumer tools available depend on the institution. See the Federal Reserve’s interagency guidance on authentication and access risk management.

A practical setup checklist
- Open the official banking app or type the bank’s known web address.
- Replace any reused or weak bank password with a unique password generated and stored by your password manager.
- Enable the strongest MFA method the bank supports; prefer a passkey or security key, then an authenticator app, over text or email codes when those choices are available.
- Save bank recovery codes as instructed and secure the associated email account with a unique password and MFA.
- Enable MFA on the password manager and understand how to recover its vault.
- Enable bank login or transaction alerts and review account activity.
