Shared 2FA for Teams
When teams share accounts—whether for work tools, client logins, or internal systems—someone has to receive the 2FA codes. That usually means one person’s phone gets every SMS verification code, and everyone else depends on them to forward OTPs. It’s slow, error-prone, and risky: personal numbers get tied to business accounts, people leave and take access with them, and there’s no clear record of who received which code.
A team 2FA solution solves this by giving you one dedicated number that receives SMS verification codes and delivers them to all approved users. MultiMFA is a multi-user 2FA service built for this: you get a shared SMS verification number, add the people who should receive codes, and stop forwarding OTPs manually. Teams use it for shared work accounts, client logins, and internal tools—anywhere multiple people need the same 2FA codes without relying on one phone. This page explains why teams need shared 2FA, the risks of manual sharing, and how MultiMFA works as a team 2FA solution.
Why Teams Need Shared 2FA
Any group that shares logins or needs access to the same accounts can benefit from a shared 2FA number. Common use cases:
Remote employees
Distributed teams need to sign into shared tools and systems. One person’s phone shouldn’t be the single point of failure for 2FA codes.
Agencies
Marketing and creative agencies manage multiple client accounts. A shared 2FA number lets the right people receive verification codes without sharing personal numbers or one shared Google Voice login.
Startups
Small teams often share one login for services like banking, ads, or infrastructure. A multi-user 2FA solution keeps access in the team instead of on one founder’s phone.
Contractors
Freelancers and contractors who need temporary access to client accounts can be added and removed from a shared number, so offboarding is clean and auditable.
The Risk of Manual OTP Sharing
Relying on one person to forward codes or sharing a single login for 2FA creates real problems:
- Forwarding SMS codes manually is slow and breaks when that person is unavailable.
- Using personal phone numbers for business 2FA mixes work and personal data and complicates offboarding.
- Shared Google Voice or similar logins mean one credential controls access for everyone—no per-user control or audit trail.
- Posting OTP screenshots in Slack or email is insecure and leaves no proper record of who accessed what.
- When someone leaves, revoking their access is harder if 2FA was tied to their personal device or a shared login.
A dedicated shared 2FA number with admin-managed recipients avoids these issues: one number receives codes, you control who gets them, and you can remove access instantly when needed.

How MultiMFA Works for Teams
- Choose a dedicated MultiMFA number. Sign up and get a dedicated SMS number that will receive all 2FA codes for your team.
- Use it when setting up SMS-based 2FA. When you enable two-factor authentication on any service (bank, ad platform, or work tool), enter your MultiMFA number as the verification number.
- Codes appear in your shared inbox and notify approved recipients. Incoming codes are delivered to your MultiMFA number and forwarded to everyone you’ve added, so the whole team gets the code without one person’s phone in the middle.
Admins control who can receive and access verification codes. For more, see our homepage and security details.
Benefits of a Team 2FA Solution
Centralized verification number
One dedicated number for all SMS 2FA codes—no more routing through a single personal phone.
Admin controls
Add or remove recipients anytime. You decide who receives codes and revoke access when someone leaves.
Reduced dependency on one phone
Shared accounts don’t depend on one person’s device. If someone is out, the team still gets codes.
Scalable user access
Plans support multiple users and higher volume so you can grow your team without changing how you handle 2FA.

|---|---|---|
| Verification number | Personal or shared login | Dedicated shared number |

Frequently Asked Questions
What is shared 2FA for teams?
Shared 2FA for teams means using one dedicated SMS verification number that delivers two-factor authentication codes to multiple approved users. Instead of one person receiving OTPs and forwarding them manually, everyone on the plan gets codes to the same shared number, so teams can access accounts without depending on a single phone.
Why do teams need a multi-user 2FA solution?
Teams need a multi-user 2FA solution when multiple people must access the same accounts (e.g. shared logins, client accounts, or company tools). Manual OTP sharing is risky and doesn’t scale. A dedicated shared 2FA number with admin controls gives teams one place to receive verification codes and control who gets them.
How does MultiMFA work for teams?
You sign up, choose a dedicated MultiMFA number, and add the team members who should receive codes. When you set up SMS-based 2FA on any service, you use your MultiMFA number. Incoming codes are delivered to that number and forwarded to all approved recipients, so the whole team gets the code without sharing personal phones.
Is shared 2FA secure?
MultiMFA uses encryption in transit (TLS) and at rest, role-based access controls, and activity logs. Admins control who can receive and access verification codes. When someone leaves the team, you remove them so they stop receiving codes immediately.
Can we try MultiMFA before committing?
Yes. MultiMFA offers a 14-day free trial (14 texts or 14 days, whichever comes first) with no credit card required. You can try the team 2FA solution risk-free and upgrade when you’re ready. See our pricing for plan details.
