Six ways to share a 2FA number with your team, and where Cleat fits

What each of these does better than Cleat

Cleat is one real US mobile line with a free team inbox. That shape is wrong for several of the jobs people come here with, and these six cover them better:

• Group2FA shares authenticator (TOTP) codes as well as texts, pushes each code to each member's own phone by notification, SMS or WhatsApp, forwards incoming voice minutes, and sells numbers well beyond the US. Cleat does none of that (Group2FA).
• Shared 2FA is built around Slack. A “profile” is a number bound to one channel, so codes appear where the team already looks, and the same shape covers authenticator and email codes. Its own FAQ is clear about the limit: “each profile is linked to one destination” (Shared 2FA).
• 2FA.group is the cheapest way in and the only one with a genuinely free tier. It also gives you an inbound email address for the services that email a code instead of texting it, and every recipient has to opt in first (2FA.group).
• Daito is a shared 2FA vault first, with groups, admin roles and a 14-day team trial. If most of your services offer an authenticator app, that is the better-shaped product, and the honest answer is to use it. Its numbers are German (Daito).
• MultiMFA tells you its numbers are VoIP before you pay, and tells you to test the services you need first. That is worth more than a guarantee, and it is the only vendor here that does it (MultiMFA).
• JoltSMS routes codes to more places than Cleat does, including Discord and Microsoft Teams, and ships an MCP server and signed webhooks alongside its REST API (JoltSMS).

The category, priced

Two things separate the prices more than the headline figures do. Most of these plans meter messages, so a busy month costs more than the row says. And most charge per member, per seat or per plan tier, so the price moves when the team does.

The number type, and who will say it

A shared inbox is useless if the service refuses the number. Two of the six publish what you are buying, and they publish opposite things. Here they are, word for word:

• Group2FA, on its non-VoIP plan

  “Non-VoIP or “Real phone numbers” are usually required by highly sensitive websites such as financial institutions, business services, or social media platforms. This type of phone number will work with ALL online services.”

  https://group2fa.app/

• MultiMFA

  “MultiMFA SMS numbers are VoIP numbers. Some platforms reject VoIP numbers, accept them but suppress security codes, or deliver codes inconsistently. The platform sending the code controls number eligibility and routing, so delivery of third-party authentication messages cannot be guaranteed.”

The second one is right, including about Cleat. No provider controls whether a service accepts a number, so no provider can promise ALL online services, and we don't. What a real mobile line changes is the line-type check that refuses internet numbers before anything else is considered: what a non-VoIP number is explains that check, and what each service actually publishes records who has written a rule down at all. Shared 2FA and 2FA.group say nothing about number type on any page we read, which means you find out by testing.

The part nobody in this category sells you

Every product here is a way for several people to read one number's codes. Almost none of them mentions what the service on the other end thinks about that. Steam does, on the same page where it refuses VoIP: “You may use the same phone number on multiple accounts. Accounts with the same phone number may be treated as the same identity with respect to the Steam Subscriber Agreement, policies, or restrictions.” It goes further — a ban on one account reaches “all other accounts that use the same phone number” (Steam).

• A shared number is a join key. Services that use a number to tell accounts apart will read shared accounts as one identity, whether or not that is what you meant.
• Read access is not ownership. Whoever can read the code can complete a login. Removing someone from the tool has to be part of offboarding, on the day they leave.
• Client accounts belong to the client. If an agency holds the number for an account in a client's name, the client loses a way to prove the account is theirs. The clean version is the client owning the line and inviting you.

Where Cleat sits

• One real US mobile line, not VoIP, with one owner whose identity is checked before the number is issued (why we verify).
• Teammates are free and uncapped. Invite the company; the price is the line. Remove someone and they stop seeing texts immediately.
• No message cap. A flat $24.99 a month, whatever arrives.
• Codes go where you already look: the shared inbox, each person's email or Telegram, a Slack or Teams channel by webhook (how that is set up), or your own systems over the API.
• It is receive-only, US-only and one number. It cannot send texts or place calls, it does not share authenticator secrets, and there is no free tier. Several products above beat it on each of those.

Which one to pick

1. 01Where the service offers an authenticator app, use one, shared through a vault your team already pays for. It is stronger than a texted code and cheaper than any number here.
2. 02If you need codes in Slack above all else, Shared 2FA is built for exactly that, and 2FA.group's free tier costs nothing to try.
3. 03If your services refuse VoIP — banks, payment processors, government portals, marketplaces — you need a real mobile line, which narrows the field to Group2FA's top plan, JoltSMS and Cleat.
4. 04If several people need the same line and the team keeps changing, compare the per-member pricing against a flat one. That is the comparison Cleat is built to win, and it is the only one we will claim.
