Why Does Letterboxd Keep Logging Me Out? Sign-In Problems and What Letterboxd Says to Do

Why does Letterboxd keep logging you out? #

Letterboxd's pages give no reason for unexpected sign-outs and do not say how long a sign-in lasts. The most relevant statement is in its Privacy Notice (last updated August 2026, read 3 October 2026): when your browser or device allows it, Letterboxd uses both session cookies and persistent cookies to keep you signed in, and many browsers can be set to decline cookies. The sign-in form also has a Remember me checkbox.

Both point at the browser. If cookies are refused in the browser's settings, or you open Letterboxd in a different browser profile, there is no stored sign-in to use. Letterboxd does not say whether that, or something on its own side, explains any particular sign-out.

The same notice also covers security. It says Letterboxd uses log data, which includes the IP address, browser type and device information, to protect the security of accounts, and that it uses monitoring tools and algorithms to detect suspicious activity and unauthorised access. It does not say what happens to a sign-in when something is flagged, such as a sign-out or a verification step.

Quick lookup: what you see and what Letterboxd says #

Keep the account's email address in working order #

Most of the recovery routes above run through the email address on the account. The Help Center says that changing the address sends a validation link to the new one and also alerts the old one, so you are told if someone makes an unauthorised change; if the link never arrived, saving the Settings page again resends it. Its article on missing emails, which covers Letterboxd's automated emails in general, names failed email authentication as the most common cause and singles out forwarding from one mailbox to another, because the receiving provider may refuse mail that appears to come from the forwarder. The fix it gives is to add robot@letterboxd.com to your contacts and to make the address on the account the one that actually receives the mail, so there is no forwarding step.

Why sign-ins collide when several accounts share one computer #

Letterboxd describes no account switcher, so the browser decides what happens. A profile holds its own cookies and saved passwords, as Chrome's help and the Chromium documentation describe, and every tab in it draws on that one store. Two people sharing a profile are sharing sign-in data too.

• Give each person their own browser profile and sign in once per profile.
• Keep passwords separate. The Terms tell each member to keep their password to themselves.
• Keep each account in one place. Because Letterboxd says it uses log data and monitoring to protect accounts, giving each account its own browser profile keeps your own sign-ins consistent. That is a sensible habit, not something Letterboxd requires or says changes how it treats a sign-in.
• Decide per computer whether to tick Remember me; Letterboxd does not publish how long a session lasts either way.
• Do not look for an explanation screen: no page read describes one.

The idea is explained in what a browser profile is, and the steps are in separating Letterboxd logins with browser profiles.

If you think someone else has your password #

1. Open the Reset password link on the sign-in form and set a password you use nowhere else. The Help Center advises a unique, complex password for each service.
2. Once you are back in, open Settings and switch on two-factor authentication with an authenticator or password manager app. Letterboxd's security notice of 15 March 2024 also recommends a unique, complex password and two-factor authentication for all members.
3. Tell Letterboxd promptly. The Terms ask members to notify Letterboxd if they suspect unauthorised activity, and the Help Center says support will try to restore access.
4. Know the limit: once an account has been deactivated and then permanently deleted, support cannot restore it.

If the account is suspended or you cannot get in at all #

1. Read any message from Letterboxd. The Terms say it tells you and gives its reasons where it can, except when it has to act at once to obey the law or protect the service.
2. Contact Customer Support through the Contact page. Give your username, the email addresses you have used and roughly when you opened the account.
3. Use the appeal route the Terms mention. For a removed review the Help Center says to contact support with the details, and support will say whether changes might lead to reinstatement.
4. Do not open another account. The Terms list working around account blocks as prohibited conduct, and a second sign-up would also fall under the rule on multiple accounts, explained in Letterboxd's rules on multiple accounts.

Where ADSSPEED fits #

ADSSPEED is a desktop app for Windows and macOS that manages many browser profiles. Because each profile keeps its own cookies, local data and browser settings, accounts you manage can stay signed in side by side without signing each other out, and clearing or losing a sign-in in one profile does not touch the others. Profiles can be opened, stopped and organised in bulk, and profile data stays on your own computer. Letterboxd's recovery steps, appeals and rules apply regardless. Use only accounts you own or are authorised to manage. ADSSPEED is not affiliated with Letterboxd.
