How to Keep Different People's Letterboxd Logins Apart on One PC With Browser Profiles

How do you keep two Letterboxd logins apart on one computer? #

Give each person their own browser profile. Chrome's help says profiles keep bookmarks, history, passwords and other settings separate, and the Chromium documentation says a profile's data includes cookies and that each profile is its own subfolder of the user data directory. Letterboxd's Privacy Notice says it uses cookies to keep you signed in when your browser or device allows it, so a Letterboxd sign-in stays inside the profile where it was made. The general idea is explained in what a browser profile is.

One rule comes first. Letterboxd's Terms prohibit using the service to create multiple accounts and tell members not to share their password. Profiles here are for separate people on a shared computer, such as flatmates, family or colleagues, who each own one account. They are not a way to run extra accounts for yourself; see can you have two Letterboxd accounts and Letterboxd's rules on multiple accounts. Use only accounts you own or are authorised to manage.

What a profile separates, and what it does not #

Set up a profile in Chrome #

1. Open Chrome on the computer and select the Profile icon at the top right.
2. Select Add Chrome profile.
3. Chrome offers to sign in with a Google Account; its help describes that as optional.
4. Choose a name, a photo and a colour for the profile.
5. In that profile's window, go to letterboxd.com and sign in with that person's own username and password.
6. To switch later, select the Profile icon and choose the profile from the list.

Edge and Firefox #

In Microsoft Edge, select the Profile icon and choose Set up a new profile. Pick Personal or Work or school, choose Sign in to sync data or Start without your data, and select Confirm and start browsing. Microsoft's help says the new profile opens in a separate Edge window and that selecting the Profile icon and then a profile switches to it.

Mozilla's Contextual Identity wiki describes Firefox Containers, now offered as the Multi-Account Containers extension. Each container gets a separate slice of the browser's storage, which the wiki lists as cookies, localStorage, indexedDB and caches. On a Firefox shared by two people, giving each person's Letterboxd tabs their own container keeps their cookies apart.

Each person's password and two-factor app #

Inside each profile the person signs in with their own username and password. If they switch on two-factor authentication in Settings, Letterboxd supports time-based one-time passwords through an authenticator or password manager app only. It offers no SMS or email codes and no backup codes, so the app that produces the codes should stay with that person, not on the shared computer. If it is lost, the Help Center's route is to reset the password using the email address on the account, or to contact support. Whether to tick Remember me is also a per-person choice; Letterboxd does not publish how long a session lasts, so nobody on the shared computer should rely on a particular duration.

Naming profiles and handing over a shared computer #

• Name and colour. Name each profile after the person who uses it and give each a different colour, so nobody signs in to the wrong account by mistake. In Chrome, select the Profile icon, then Manage Chrome profiles, pick the profile, and choose More and Edit; or choose Customize profile for the profile you are in.
• Passwords. Each person saves only their own Letterboxd password and never passes it on, which matches the Terms' rule that a member keeps their password to themselves.
• When someone stops using the computer. Remove their profile. In Chrome: Profile icon, Manage Chrome profiles, the profile, More, Delete, then confirm. Chrome's help warns that the profile's saved bookmarks, history and passwords, along with its other settings, are then wiped from the computer. In Edge: Profile icon, Profile settings, More profiles, the delete button, then Remove profile.
• A new person. Give them a new profile and their own account. Handing over a profile that is already signed in would amount to sharing a login.

Backups: use Letterboxd's own export #

According to Letterboxd's Help Center (read 3 October 2026), Settings has an account export that packs the whole account into a single ZIP archive of CSV files. The archive also covers deleted content and reviews of films that have since been removed from the site. The owner should save the file somewhere only they can open, not in a folder everyone on the computer can reach. Letterboxd's page on importing data describes CSV imports in its own format and from IMDb and other sources, with a file-size limit of 1 MB per upload; it does not say whether an export can be re-imported into another account.

If it does not work #

• You are signed out every time. Check the browser's cookie settings and that you are using the same profile. See why Letterboxd keeps logging you out.
• Someone signed in to the wrong account. Give the profiles distinct names and colours, and remove any saved password that belongs to someone else.
• A profile was deleted by mistake. Its saved passwords are gone, but the Letterboxd account is not. Use the password-reset route: the reset email goes to the address on the account and includes the username.

Where ADSSPEED fits #

ADSSPEED is a desktop app for Windows and macOS that manages many browser profiles. Each profile keeps its own cookies, local data and browser settings, so accounts you manage can stay signed in side by side without signing each other out. Profiles can be opened, stopped and organised in bulk, a proxy can be set per profile or assigned to many at once, and profile data stays on your own computer. Setup is in installing ADSSPEED on Windows. It does not change what Letterboxd permits, including its rules on multiple accounts and shared passwords. Use only accounts you own or are authorised to manage. ADSSPEED is not affiliated with Letterboxd.
