Hidden Costs Breakdown

1

Telephony and SMS Fees

medium overage

Duo charges separately for SMS and voice-based authentication methods, typically ranging from $0.05 to $0.15 per authentication.

industry

Hardware Tokens: While Duo supports software-based authentication, organizations requiring hardware tokens (e.g., YubiKeys) must purchase these separately.

Device Registration Overages

medium overage

Overage fees may apply if users manage more devices than the default limit of 10 per user included in each Duo tier.

industry

Seek Multi-year Commitments: Committing to multi-year terms (e.g., 2-3 years) can result in more favorable per-user pricing and stronger discounts, particularly for larger deployments (1,000+ users).

3

Professional Services

high implementation

Implementation, directory integration, and custom policy configuration are often quoted separately.

Onboarding & SMS Activation Friction

low implementation

Multiple reviewers report hiccups during user onboarding, including SMS activation links that sometimes fail to deliver on internal corporate networks. This translates into additional IT help-desk time and potential rollout delays.

trustradius

Cons: Hiccups in onboarding.

trustradius

There are some issues with sending activation links through text (sometimes don't come through on our internal network)

7

Documentation & Training Gaps

low training

Reviewers consistently flag insufficient documentation and manuals as a con. Organizations may need to invest internal IT time or engage third-party consultants to fill gaps, especially for complex or large-scale deployments.

trustradius

Cons: Better documentation.

trustradius

Cons: Manuals

8

IDP Integration Complexity

medium integration

Reviewers cite Identity Provider (IDP) integration as a notable con. Organizations with existing identity infrastructure (e.g., Okta, Azure AD) may need additional engineering time or professional services to complete the integration cleanly.

trustradius

Cons: IDP

9

Microsoft MFA Redundancy

medium addon

Organizations that also license Microsoft Entra ID (formerly Azure AD) MFA may end up paying for overlapping authentication capabilities. One reviewer specifically flagged the lack of a clear priority mechanism between Duo and Microsoft's built-in MFA, implying potential redundant spend.

trustradius

Competing with Microsoft, there should be a way to make one or the other a priority.
