You got an email about a new sign-in

The "New sign-in to your WŬMÙ account" email arrives on every new sign-in to your account — including when you sign out and back in on your own device. If it was you, there is nothing to do.

The email shows the device and the time, and has an "Open Devices" button.

If it was not you

1. Click "Open Devices" in the email — the Security tab opens.
2. Find the device you do not recognise and click "End".
3. Change your password in "Change password" on the same tab.

Changing the password signs every other device out.

When there is no email

• after sign-up — it is the first sign-in;
• when you sign in to the mobile app by confirming it from a browser you were just using;
• when there are many sign-ins in a row — at most five emails an hour.
