In MetaMask login screen, under the "Unlock" button, there is a message that says "Restore account?". If you click the message "Import account using seed phrase" you can import your old account.

If you are logged on and want to close in the account's menu in the top right there is a button "Lock" that will bring your to the login screen, where you can click the "Import account using seed phrase".


If you want only logout metamask, click on metamask icon, click on 'my accounts' icon in the top right, and within this window you'll find the logout button.
