With the new(ish) Containers feature, you can have different accounts in different tabs. They are color-coded so you can tell which container each tab is in. Just long-press or right-click the New Tab button to choose which container the new tab opens under. So e.g. you could log in to Twitter in your container, open a new tab in her container, and log in to a different Twitter account there.
