* docs(wiki): correct the install and operations pages for 4.0.0 Quick Start passed docker an empty ENCRYPTION_KEY: an assignment prefix is not expanded on the same command line, so the server silently generated its own key instead of taking the one the page told you to set. The tag examples pinned to the 3.x line, the documented tmpfs size did not match the shipped compose file, and several .env values were described as reaching the container when compose never interpolates them. * docs(wiki): match the MCP reference to the registered surface The scope table was missing the whole Collections group and the totals said 27 scopes across 13 groups where the code registers 29 across 14. The Cloudflare link on the setup page pointed at an anchor on its own page instead of the heading on Troubleshooting. * docs(wiki): correct the plugin and admin pages Three links to Plugin-Development carried a .md suffix, which does not resolve on the wiki. The admin pages described tabs, permissions and storage behaviour that had moved on. * docs(wiki): bring the feature pages back in line with the app Costs still documented the old panel, where categories could be added, renamed, reordered and deleted; they are fixed now and the panel is a day-grouped ledger with settlements. Trip sharing, journeys, maps, packing, reservations and the account pages had all drifted in the same way. * docs(wiki): cover the pages the first pass did not reach The MCP catalog listed 168 of the 201 registered tools; the settlement tools and rate_place were missing here and the Collections family from the addon page. Several resource rows claimed a trips:* scope where the handler asks for trips:read. * docs(wiki): tighten the corrections a review picked apart The audit-log resource is the row id, not the credential id; an admin password reset does not bump password_version the way the page implied; and a few of the new paragraphs described behaviour more confidently than the code supports. * docs(wiki): fix what a last read-through caught Costs shows every figure in your display currency, not the trip's, and an expense with no payer still counts against the members it is split between. Studio's cutoff is a 1024px viewport rather than phones alone, and the Integrations tab is gated on the providers an admin has configured. * docs(wiki): the last few the review caught A passkey satisfies the MFA policy everywhere except the WebSocket handshake, which still asks for TOTP, so a passkey-only account under that policy gets no live updates. Mobile optimizes a day from two places, not three. The ctx.db row carried an unescaped pipe that split the table, and the Backups table linked with a wiki link whose pipe did the same.

Two-Factor Authentication
What it is
TREK supports Time-based One-Time Password (TOTP) two-factor authentication, compatible with Google Authenticator, Authy, 1Password, and any standard TOTP app. When 2FA is active, you enter a 6-digit code (or a backup code) after your password on each login.
Setting up 2FA
Go to Settings → Account, find the Two-factor authentication (2FA) section and click Set up authenticator.
- A QR code and a text secret are displayed. Scan the QR code with your authenticator app.
Note: The setup session expires after 15 minutes. If you do not complete setup within that window, start again.
- Enter the 6-digit code shown in your authenticator app and click Enable 2FA.
- Save your 10 backup codes. These are single-use codes shown only once — store them somewhere safe (a password manager, printed paper). Each code has the format
XXXX-XXXX. - 2FA is now active on your account.
Logging in with 2FA
After entering your email and password, TREK shows a second prompt for your TOTP code. You have 5 minutes to complete this second step before the intermediate session token expires. Enter either:
- The current 6-digit code from your authenticator app, or
- One of your backup codes (format
XXXX-XXXX). Each backup code can only be used once.
Disabling 2FA
Go to Settings → Account and use the Disable 2FA form. You must provide both:
- Your current account password
- A valid TOTP code from your authenticator app
Note: You cannot disable 2FA while the admin has required it for all users (see below). Owning a passkey does not lift that restriction.
Admin-enforced 2FA
An admin can require 2FA for all users. Before enabling this setting the admin must have secured their own account with either an authenticator app or a passkey — the server rejects the change otherwise with Secure your own account with two-factor authentication or a passkey before requiring it for all users.
If the setting is active and your account has neither 2FA nor a passkey, any API request after login returns a 403 error and the client redirects you to Settings → Account with a prompt to complete 2FA setup. You cannot use the app until setup is complete. See Admin-Permissions.
A user-verified passkey satisfies this policy the way a TOTP authenticator does: with at least one passkey on your account the API stops blocking you and you never need an authenticator app. That holds even if an admin later turns passkey login off again — an existing passkey keeps satisfying the policy. Real-time sync is the one exception: the WebSocket handshake accepts only TOTP, so a passkey-only account under this policy can use TREK normally but never receives live updates from other members. Nothing tells you — the client simply keeps retrying the connection.
Whether enrolling a passkey is a way out of the lockout depends on the instance. Passkey login is off by default (see Passkeys); where an admin has turned it on, the enrolment endpoints stay reachable while the rest of the API is blocked, so you can add a passkey from Settings → Account instead of setting up an authenticator app. Where it is off, TOTP setup is the only way to unblock yourself — or ask an admin to reset your 2FA.
Admin: You can reset 2FA for a locked-out user from the admin panel. See Admin-Users-and-Invites.
Rate limits
TREK enforces IP-based rate limits to protect against brute-force attacks:
| Endpoint | Limit |
|---|---|
Login (/api/auth/login) |
10 attempts per 15 minutes |
MFA code verification (/api/auth/mfa/verify-login) |
5 attempts per 15 minutes |
Exceeding a limit returns HTTP 429. Wait for the window to reset before retrying.
Demo users
The demo user account cannot enable or disable MFA.
