Embracing the Benefits of Passwordless Authentication

We enforce two-step login, also known as multi-factor authentication, across every account we manage. It’s the single most effective security control most businesses can put in place, and it’s something we talk about often.

Passwordless authentication takes the same underlying idea a step further: removing the password from the login process entirely.

What is passwordless authentication?

Passwords are, by a wide margin, the weakest part of most login processes. They get reused across accounts, written down, shared, and guessed. Passwordless authentication replaces the password itself with something stronger: a registered device, a biometric check like a fingerprint or face scan, or a security key, combined with the same second-factor verification already used in standard MFA.

In practice, this usually means a user logs in by approving a prompt on their phone, or using Windows Hello or Face ID on their device, rather than typing a password at all.

Why this matters

It removes the weakest link. A password that doesn’t exist can’t be guessed, reused, phished, or leaked in a data breach. A significant proportion of account compromise attempts rely on a stolen, weak, or reused password as the starting point. Removing the password removes that entry point entirely.

It reduces help desk pressure. Password reset requests are one of the most common categories of helpdesk ticket. Removing passwords from the login process for supported accounts reduces this overhead, freeing up time for issues that actually need a person to look at them.

It’s more convenient, not less secure. A common misconception is that better security means more friction. Passwordless authentication is typically faster for the end user — a face scan or a device prompt takes less time than typing and remembering a complex password — while being significantly harder to compromise.

How this fits with what we already manage for you

For Network Fish managed support clients, we already enforce multi-factor authentication across every account and platform. Passwordless authentication builds directly on top of this, rather than replacing it, since the strongest setups combine a passwordless login method with the same device-based or biometric verification used in MFA today.

For clients on Microsoft 365, this is particularly relevant. Microsoft Entra ID, the identity and access platform we configure and manage as part of your Microsoft 365 security, includes native passwordless authentication options, including Windows Hello for Business, the Microsoft Authenticator app, and FIDO2 security keys. For many businesses, the path to passwordless doesn’t mean buying new software — it means properly configuring capability that’s already included in your existing Microsoft 365 licence.

Is passwordless authentication right for your business?

It’s worth considering if:

  • you’re already enforcing MFA and want to take the next step in reducing password-related risk
  • your team frequently raises password reset requests with your helpdesk
  • you’re reviewing your Microsoft Entra ID configuration as part of a broader security review

We assess this as part of your Microsoft 365 security configuration, and can advise on whether moving towards passwordless authentication makes sense for your business, and what that would involve in practice.

FAQ

Common questions

What is passwordless authentication?

Passwordless authentication is a way of logging into an account without typing a password. Instead, the user verifies their identity using a registered device, a biometric check such as a fingerprint or face scan, or a security key, usually combined with the same second-factor verification used in standard multi-factor authentication. Common examples include approving a login prompt on a phone, or using Windows Hello or Face ID on a device.

Is passwordless authentication the same as multi-factor authentication?

They’re related but not identical. Multi-factor authentication adds a second verification step on top of a password. Passwordless authentication removes the password from the process entirely, replacing it with a stronger method such as a device prompt or biometric check, often still combined with a second factor for additional security. The strongest setups use both together: no password, plus a verified device or biometric, plus a second factor.

Is passwordless authentication actually more secure than a password?

Yes, significantly. Passwords are routinely reused across accounts, written down, shared, guessed, or exposed in data breaches. A password that doesn’t exist can’t be stolen, reused, or phished. Removing the password removes one of the most common entry points attackers rely on to compromise an account.

Does passwordless authentication require new software or hardware?

Not necessarily. For businesses already using Microsoft 365, Microsoft Entra ID includes native passwordless authentication options, including Windows Hello for Business, the Microsoft Authenticator app, and support for FIDO2 security keys, all included within most Microsoft 365 licences. For many businesses, enabling passwordless authentication is a configuration step rather than a new purchase.

Will passwordless authentication make logging in more complicated for our team?

Generally, the opposite. Most passwordless methods — a fingerprint, a face scan, or approving a prompt on a phone — are faster than typing a password, particularly a strong, unique password as recommended security practice requires. Users typically find passwordless login both quicker and easier than the password-based process it replaces.

Can passwordless authentication reduce IT support costs?

It can. Password reset requests are one of the most common categories of helpdesk ticket for most businesses. Reducing reliance on passwords for accounts that support passwordless login reduces this volume, freeing up support capacity for issues that genuinely require attention.

Is passwordless authentication included in a Network Fish managed support contract?

Microsoft 365 security configuration, including assessment and setup of passwordless authentication options through Microsoft Entra ID, is available for Network Fish managed support clients as part of your Microsoft 365 security service. Speak to us about reviewing your current setup.
