Frequently asked questions
What is MultiMFA SMS?
MultiMFA SMS is shared MFA for text-based verification codes. You get a dedicated phone number, use it on accounts that send login codes by SMS, and approved users receive those codes from one secure dashboard.
How does MultiMFA SMS work?

Who is MultiMFA SMS designed for?

How much does MultiMFA SMS cost?
MultiMFA SMS includes a free trial, then paid tiers starting at $5/month. Plans scale by users and included monthly text volume, with Team and Organization options for larger groups.
Will MultiMFA SMS work with every platform?
No SMS or VoIP provider can guarantee third-party authentication delivery. Some platforms reject VoIP numbers, suppress security codes, or deliver them inconsistently. Test each exact workflow with the free trial before purchasing. If a platform blocks VoIP or requires a real mobile number, request the MultiMFA SMS (Cell) pilot. If a platform requires app-based MFA, use MultiMFA TOTP or MultiMFA Authenticator.
What is MultiMFA SMS (Cell)?
MultiMFA SMS (Cell) is coming soon. It will provide a dedicated carrier-issued mobile number for MFA workflows where VoIP numbers are unsupported or unreliable. Authentication messages are received on a real cellular number and relayed through MultiMFA to authorized users.
When will MultiMFA SMS (Cell) be available?
MultiMFA SMS (Cell) is currently Coming Soon. We are collecting interest now and will contact waitlist members as availability opens. No launch date is promised.
What is the difference between MultiMFA SMS and MultiMFA SMS (Cell)?
MultiMFA SMS is available today and uses a dedicated VoIP-based number. MultiMFA SMS (Cell) is coming soon and will use a dedicated carrier-issued mobile number for services that restrict or prefer real mobile numbers.
Why do some services reject VoIP numbers?
Some banks, financial institutions, Microsoft, Amazon, AWS, and other security-sensitive services may restrict VoIP numbers for authentication to reduce fraud and improve delivery reliability. Policies vary by provider and can change.
Will MultiMFA SMS (Cell) work with my bank, Microsoft, Amazon, or AWS?
MultiMFA SMS (Cell) uses a dedicated carrier-issued mobile number rather than a VoIP number, improving compatibility with services that restrict or reject VoIP-based MFA delivery. Some banks, financial institutions, Microsoft, Amazon, AWS, and other security-sensitive services may restrict VoIP numbers. Third-party compatibility and delivery policies can change, so acceptance by a particular provider cannot be guaranteed.
Can MultiMFA guarantee compatibility?
No. MultiMFA cannot guarantee acceptance or delivery by every third-party provider, and provider authentication policies may change without notice.
How many relay users will MultiMFA SMS (Cell) support?
Planned support is up to 20 relay users. Final commercial terms may change before general availability.

Planned launch pricing is a $250 one-time setup fee plus $900 prepaid annually ($75/month equivalent) on a 12-month term. First year $1,150; renewal $900/year. Pricing and service terms are subject to change before general availability.

Need app-based codes instead of SMS?
