# How to Check and Revoke a Device If you notice a device you do not recognize, or if you have lost a device (e.g., a lost phone), you should revoke its access immediately. **Here is a guide on checking and revoking a device:** Device management page link: Navigate to the avatar photo in the upper right corner, and click the '**Settings**' option.
On the profile page, click the '**Security**' option and select '**Device Management**'.
Check the list of active devices. Compare the location and last login time with your own activity.
Locate the suspicious or old device and click the '**Revoke**' button next to it, and then confirm the revoke process.
After confirming, the device will be logged out immediately. If that device wants to log in again, the login password or verification code will be required.
**⚠️ Security Advice:** If you find a device you do not recognize (e.g., a login from a foreign country you haven't visited), simply revoking it is not enough. The better way is you need to change your login password immediately to prevent the intruder from logging back in.
