Why do I keep getting a new sign-in notification?

When Basecamp detects a login from a device it hasn't seen before, it sends you an email to let you know. This is a security feature, it's how you'd find out if someone else accessed your account. After the first login from a device, you typically won't hear about it again.

The email comes from support@basecamp.com with a subject like "New sign in for Basecamp from Chrome on Windows." It includes the browser, operating system, IP address, and time of the login.

⚠️ If you think someone else accessed your account, change your password and change your password right away. You can also review your Launchpad Activity Log to audit recent logins.

Why you might keep getting this email

Each time you log in, Basecamp sets a cookie in your browser to remember your device. If that cookie gets cleared, Basecamp treats your next login as a new device and sends another notification.

Common reasons the device cookie might be getting cleared:

Your browser is set to clear cookies automatically
You're browsing in private or incognito mode
You manually cleared your browser cookies
You switched to a different browser
You reset your browser, computer, or phone

Because this is a security alert, there's no way to turn it off from within Basecamp.

If your browser is set to block or automatically clear cookies, you'll need to log in again every time you open it and you'll get a new notification each time. Check your browser's settings below:

Allow Basecamp cookies while clearing others

If you need to keep clearing cookies regularly, you can set most browsers to always allow cookies from Basecamp specifically while still clearing everything else.
