This article clearly explains how to switch Claude accounts on the web and mobile, log in on multiple devices, and handle session desync caused by an incomplete sign-out. Follow the steps and you can basically avoid the awkward situation of “I clearly switched accounts, but I’m still in the same conversation.”
Preparation: First confirm which login method you’re switching from
Common Claude login entry points involve opening the official site in a browser and completing an authorized sign-in, usually via an email verification code or a third-party account. Before switching accounts, first note which method your current Claude login is using; otherwise, it’s easy to end up in a situation where “you think you switched accounts, but it’s actually still the same authorization.”
If you have multiple email addresses registered with Claude, it’s recommended to assign a fixed login method to each account (for example, always use email verification codes). This makes switching more straightforward later and reduces the chance of mixing up accounts.
Switching Claude accounts on the web: Properly signing out is more crucial than just closing the page
When switching accounts on the Claude web app, prioritize signing out using the in-site logout option, then close the tab. Simply closing the page or only clearing browser tabs may allow Claude to keep you logged in, so the next time you open it, it may automatically return to the original account.
After signing out, log in again with the target account. If the browser auto-fills the old account information, cancel auto-fill first and then enter the new account. If, after signing out, it still automatically logs into the old Claude account, it’s usually because the browser has retained the third-party authorization state—you’ll need to sign out there as well on the authorization page.
