About Multifactor and its alternatives
Multifactor is a service for sharing online accounts with people and AI agents without sharing the underlying password. According to its site, you set what a shared link can do, see every action in a live log, and can end access at any time. Its homepage also describes a post-quantum, zero-trust design where its servers only ever see ciphertext.
When comparing alternatives in this category, weigh the pricing structure first, since some tools charge per user, some per usage, and some only on request. Check which regions and currencies a vendor publishes prices for, which integrations it supports, how much support is included, and what the contract terms require. Also check whether the tool is built to share existing accounts or to build login into your own software, because those are different jobs.

- Free tier covers up to 10 users

- Consumption-based
- Category
- Developer Tools

Where it falls short

FAQ
Questions about Multifactor alternatives
What is the best alternative if I mainly need to share one account with my team?
The entries in this list focus on different jobs, so none is a direct substitute for sharing a single login. Okta and Duo Security manage workforce logins across many company apps, which is broader than one shared account. Teams that only need to add a second login step to their own accounts can look at Authy, which is free.
Which alternative has a free option?
Duo Security has a free tier that covers up to 10 users at $0 per user per month, plus a 30-day free trial of its paid editions. Authy is free to download and use, and the site does not publish a pricing page. Twilio offers a free trial that needs no credit card to start.
Which alternative is best for AI agents?
Auth0 describes controls for AI agents and MCP tools, including fine-grained authorization, so it is the entry most focused on agent access. Okta also lists AI agent identity alongside workforce and customer identity. Both are aimed at developers and organizations managing identity at scale.
How do the prices compare?
Okta lists Starter at $6, Core Essentials at $14, and Essentials at $17 per user per month, with higher tiers quoted on request. Duo lists Essentials at $3, Advantage at $6, and Premier at $9 per user per month. Auth0 and Authy do not publish pricing on their sites, and Azure CycleCloud charges on consumption, so its cost depends on the compute you use.
Do these alternatives support enterprise compliance and single sign-on?
Okta and Duo Security both offer single sign-on and centralized access controls for companies. Auth0 offers enterprise SSO, SCIM, and organization support for B2B products. Multifactor's site lists advanced auditing, SSO, and dedicated support on its Enterprise plan, so compare those specific features against the entries before deciding.
