## Verified facts

Checked against Mattermost's own documentation on 2026-08-19. Fields absent below are ones Mattermost does not document, not ones we assumed.

| Field | Value |
|---|---|
| Reset by email | yes |
| The email contains | a link |

## Steps

1. **Open the sign-in page** at mattermost.com and choose "Forgot password?". Some sites label this "Can't log in?" or "Trouble signing in?".
2. **Enter the email address on the account.** If you are not sure which address that is, search your inboxes for mail from mattermost.com; the inbox holding those messages is the account email.
3. **Open the reset email and follow its link.** Links are single-use and short-lived; if nothing arrives in a few minutes, check spam and confirm the address.
4. **Choose a strong new password.** 16+ random characters, and never one used anywhere else.
5. **Store it somewhere sealed**: a password manager or encrypted vault, not a note and not a screenshot.

## Common problems

- **Full disk on server blocks password reset functionality.** When the Mattermost server reaches 100% disk utilization, password reset emails may not be delivered or reset links may expire before delivery.

- **SSO accounts cannot reset password through Mattermost.** When using SSO authentication, the password reset feature does not inform the user that they cannot reset their SSO account through Mattermost. (https://docs.mattermost.com/administration-guide/configure/experimental-configuration-settings.html)
- **Mattermost is often self-managed, so Mattermost Inc cannot reset passwords for users.** Because Mattermost is self-hosted by organizations, Mattermost staff cannot access user instances or reset passwords for end users.

## Doing it automatically

Repass connects to Gmail once, finds the accounts you have, and runs this flow for you in your own browser. Passwords are generated on your device and encrypted before they are stored; Repass also holds a key that can unwrap the vault, so signing in is enough to open it. It pauses and hands over when a site asks for a CAPTCHA or a code.
