Share Auth, 1Password or Bitwarden for sharing 2FA?

1Password and Bitwarden are excellent password managers, and both can store a TOTP secret in a vault item and share it with a team. Share Auth does one thing: share 2FA codes. Three differences matter when several people need the same code.

1. Who receives the seed

In a password manager, the shared item is decrypted on each member’s device, seed included, so that the app can compute the code.

• 1Password Teams has only three vault permissions; “Allow Viewing” already lets people view and copy passwords (source).
• 1Password Business adds a “View and Copy Passwords” permission, which 1Password classes as enforced by the client: the unencrypted data stays on the device and can be extracted from it (source).
• Bitwarden offers “hidden passwords” collections that prevent viewing or copying the TOTP seed, while stating that these hidden fields limit access without preventing it (source).

In Share Auth, the code is computed on the server. A reader receives the current code, never the seed: it never reaches their device, so there is nothing to extract.

2. What is logged

• 1Password keeps its activity log and usage reports for the Business plan (source).
• Bitwarden offers event logs on the Teams and Enterprise plans; their list of events has no event specific to viewing or copying a TOTP code (source).
• Share Auth records every code given out, on every plan: who, which account, when, and through which channel (website, API, Slack, Discord or Teams).

3. Where the code arrives

Password managers show the code in their apps and fill it in the browser. 1Password’s Slack integration posts alerts and sign-in notifications; its documentation describes no way to get a code in Slack (source).

Share Auth brings the code to where the team asks for it: /otp in Slack or Discord, the API for a script, the MCP connector for an AI agent, and the browser extension on the sign-in page.

Pricing

Which one to choose?

Choose a password manager if your main goal is managing the team’s passwords; that is its job, and it will store 2FA codes as well. Add Share Auth when people need to use a code without holding the secret, when you need to know who got which code, or when the code has to arrive in Slack, Discord or a script.
