Google Authenticator. Authy. Microsoft Authenticator. These apps are excellent — for individual users managing their own accounts. But IT teams have fundamentally different needs, and no personal authenticator app is designed to meet them.
This article breaks down what makes an authenticator solution truly suitable for teams, compares the most popular options, and explains why a dedicated MFA vault is often the right answer for organizations.
What Personal Authenticator Apps Are Missing
Personal authenticator apps were designed with one user in mind: you, on your phone, for your own accounts. They do this well. But the moment a second person needs access to the same OTP code, the architecture falls apart.
Here's what's missing:
No shared access. There's no way to give a colleague access to a specific code without handing them your phone — or sharing the underlying secret through an insecure channel.
No access control. If you share a vault, everyone sees everything. You can't say "Alice can see AWS codes but not Stripe."
No audit trail. Personal apps don't log who accessed what, when. For compliance and incident response, this is a significant gap.
No offboarding. When someone leaves, you can't revoke their access to shared OTP codes. You'd need to regenerate and re-enroll every code they had access to.
Device dependency. If the person who holds the authenticator app is unavailable, or their phone is lost or broken, the team loses access to critical systems.
Comparing Popular Authenticator Options for Teams
Google Authenticator
Best for: Individual users with a few personal accounts.
Google Authenticator is simple, reliable, and widely supported. It added backup via Google account in 2023. But it still doesn't support shared access, team management, or audit logging. Not suitable for team use.
Microsoft Authenticator
Best for: Organizations deeply integrated into the Microsoft 365 ecosystem.
Microsoft Authenticator integrates well with Azure AD and supports passwordless login for Microsoft services. For shared OTP codes across non-Microsoft services (AWS, GitHub, Stripe), it offers no team-specific features.
Authy
Best for: Individuals who want cloud backup and multi-device access.
Authy's encrypted cloud backup and multi-device sync are genuinely useful. But it's designed for personal use. There's no team management, no per-token access control, and no audit logging.
1Password / Bitwarden (TOTP in password manager)
Best for: Teams already using these password managers and wanting consolidated access.
Both 1Password and Bitwarden support storing TOTP seeds alongside passwords. This is a meaningful improvement over personal phones for teams — vault access is managed, and secrets are encrypted.
The limitation: TOTP access is all-or-nothing at the vault level. You can't say certain people can access AWS codes but not Stripe codes. And audit trails are limited for the TOTP feature specifically.
Dedicated team MFA vault (e.g., Gatera)
Best for: IT teams and MSPs that need granular access control, audit logs, and instant revocation.
A purpose-built team MFA vault addresses all the gaps above:
- Per-code access control — decide who can view or use each individual OTP
- Full audit logging — every access event logged with timestamp and user
- Instant revocation — remove an employee's access in seconds
- No device dependency — codes live in the vault, not on personal phones
- Team management — add members, assign roles, organize by team or client
This is the appropriate solution for organizations that treat authentication as a security-critical function.
The Real Cost of Using the Wrong Tool
The cost of an inadequate authenticator solution often doesn't show up until something goes wrong:
- An employee leaves and takes the only copy of the AWS OTP seed with them.
- A security audit reveals no way to prove who accessed which accounts.
- A personal phone is lost and recovery takes days, during which the team can't log in.
- A disgruntled ex-employee retains access because no one knew which codes to rotate.
These aren't hypothetical. They happen regularly, and they happen because organizations adopt personal authenticator tools without considering the team-level implications.
What to Evaluate When Choosing a Team Authenticator
When evaluating authenticator solutions for your organization, prioritize:
- Shared access model — can multiple people access the same OTP without sharing a phone?
- Granular permissions — can you control access per user and per code?
- Audit trail — is every access event logged with user and timestamp?
- Revocation speed — how quickly can you remove a user's access?
- Backup and recovery — can you recover codes if a device is lost?
- Integration — does it support standard TOTP/HOTP so it works with any service?
Conclusion
For individual use, Google Authenticator or Authy work fine. For teams — especially IT departments and MSPs managing credentials across multiple clients — a personal authenticator app is the wrong tool for the job.
A dedicated team MFA vault gives you the access control, audit trail, and management capabilities that personal apps were never built to provide.
