Google Chrome makes computer-sharing safer with default-to-guest feature
Protect multi-user computers by defaulting Google Chrome to guest mode

Whether it's in a library, school or other organization, shared computers are generally a part of business as usual.
One big issue that's long impacted this shared-computer system is when a user would log on to Google Chrome and forget to log off after their session. This would result in the next user potentially having access to the previous user's Google account and search history.
However, Google has fixed that with a new default-to-guest feature. When you set up default-to-guest mode, either as an enterprise policy or command-line switch, it prevents this user overlap by defaulting to the guest mode in each session. So, no longer are you reliant on honesty prevailing and users logging the last person out if they forgot.
When Google Chrome is in guest mode, it will not save any browsing data, including:
- Websites you visit
- Websites you sign in to
- Search history
- Search suggestions
