Compare Passkeys, Passwords, MFA, SSO, Windows Hello, and NIST Guidelines
Curious if traditional passwords are still up to the task? Wondering if passkeys, multi-factor authentication, single sign-on, or Windows Hello can make your life easier and safer? Get ready to explore how these options measure up when it comes to convenience, setup, and protecting your data. Keep reading to discover which approach is best for your situation.
Introduction to Passkeys, Passwords, MFA, SSO and Windows Hello
Keeping your data safe and ensuring that only the right people have access is a top priority for any organization. If you run a business or manage sensitive information in areas like healthcare, law, or accounting, you know how important it is to protect both clients and employees from account breaches. This post will help you understand five popular authentication methods and see how they stack up in terms of ease of use, setup, and overall security.
Passwords
- What They Are: A string of characters used to log in to your accounts.
- Ease of Use: Most people are familiar with passwords. You simply type them in and hit enter.
- The downsize is that memorizing a different one for every account can get difficult.
- Ease of Configuration: Setting up passwords is straightforward—just enter a new password. However, good password habits (long, unique, and hard to guess) need more effort.
- Following updated NIST guidelines means using passphrases instead of short, complex strings.
- Security: A string of characters used to log in to your accounts.
- Susceptible to phishing, brute force attacks, and password reuse problems.
- Strong passwords and password managers can help, but passwords alone aren’t the strongest defense.
Example/Use Case: A small medical clinic in Kettering might assign staff different logins for patient record systems. Using only passwords can put patient data at risk if employees reuse personal passwords from social media sites.
Passkeys

- What They Are: Passwordless credentials stored on a trusted device, such as your smartphone, that rely on public-key cryptography.
- Ease of Use:
- Logging in usually just requires a biometric check (fingerprint or face recognition) on your phone or computer.
- You don’t have to remember a string of characters.
- Ease of Configuration:
- Setting up a passkey is simple if your device and the online service support it. You enroll once, and your device stores it securely.
- Security:
- Very strong. Hackers can’t easily steal a passkey the same way they steal passwords.
- Reduces the risk of phishing because there’s no password to trick you into revealing.
Example/Use Case: An accounting firm in Dublin could let employees log in to cloud-based bookkeeping software using a passkey on their smartphones. This prevents unauthorized access if a password is leaked.
Multi-Factor Authentication (MFA)
- What It Is: Uses at least two ways to verify your identity (password + code from your phone, or password + fingerprint, and so on).
- Ease of Use:
- After initial setup, logging in usually involves entering your password, then confirming a code or biometric factor.
- It takes a few extra seconds, but it’s more secure than a single password.
- Ease of Configuration:
- Most modern platforms (Microsoft 365, Google Workspace, etc.) walk you through an MFA setup wizard.
- Users need a smartphone or another verification method (like a hardware token).
- Security:
- Provides strong protection because even if someone gets your password, they still need the second factor.
- Common second factors include text messages, authenticator apps, or biometric checks.
Example/Use Case: A law firm in Beavercreek might require attorneys to enter a password and confirm a code on their phones to keep sensitive case files secured.
Single Sign-On (SSO)
- What It Is: Lets you log in once and access multiple apps without typing credentials again. Think of signing into your Microsoft or Google account and instantly getting into all associated services.
- Ease of Use:
- Very convenient. You just log in once per session, and then jump between email, file storage, and other business apps.
- Ease of Configuration:
- Requires setup by an IT admin or provider like Capstone Technologies Group. They’ll connect your apps to a single identity provider (IdP).
- End users experience a simpler login process once it’s in place.
- Security:
- Reduces the number of passwords you need to remember.
- Strongly recommended to combine SSO with MFA to make it even safer.
Example/Use Case: A marketing agency in Grandview can use SSO to let employees access design tools, email, and shared documents with just one login. If they add MFA, it’s even more secure.
Windows Hello
- What It Is: A built-in feature in Windows 10 and Windows 11 that lets you unlock your device or apps using biometrics (face, fingerprint) or a PIN.
- Ease of Use:
- Very quick. You look at the camera or tap your fingerprint reader.
- No need to memorize anything beyond a fallback PIN if biometrics aren’t available.
- Ease of Configuration:
- Simple, guided steps in Windows Settings.
- For business use, your organization’s IT department or provider will handle policies and device compatibility.
- Security:
- Uses a Trusted Platform Module (TPM) for secure key storage.
- Harder for attackers to break in compared to a basic password.
Example/Use Case: A healthcare office in Springfield with Windows 11 PCs can set up Windows Hello to make logins faster while protecting patients’ electronic health records with biometric checks.
Which One Is Right for You?
Choosing the best option depends on your situation. Many organizations in the Dayton, Columbus, and Cincinnati areas mix MFA and SSO to simplify sign-ons while adding extra security. Others adopt passkeys or Windows Hello for a near-passwordless experience. The key is finding a balance between convenience and protection, especially if you’re handling confidential files for clients.
