Profiles per space
Profiles in Rio keep your accounts apart. Each profile has its own history, logins, cookies and extensions, and any space can use any profile. Put your Work space on a work profile and your Home space on another, and each stays signed in to its own accounts. Rio is a free, open-source browser for Mac.

Two Google accounts, no signing out
You have a work Google account and a personal one. Your Work space runs on a Work profile and your Home space on a Personal profile. At six you swipe from Work to Home and Gmail there shows your personal inbox. Nobody signed out, nothing asked which account. Swipe back and the work inbox is where you left it.
What a profile keeps
Each profile has its own:
- History
- Logins: saved passwords, cookies and the sites you are signed in to
- Extensions
- Favorites, shared by every space on that profile
- Search engine: Google, DuckDuckGo, Bing, Brave or Ecosia
- Archive time for Today tabs: 12 hours, 24 hours, 7 days or 30 days
- Download folder
Spaces on the same profile share all of it. That suits two spaces for one job, say Launch and Support, that use the same accounts.
Put a space on its own profile
- Go to the space and press Cmd+T, then run Edit Space.
- Under Profile, pick a profile, or pick New profile and type its name.
- Click Save. If the space already has tabs, Rio asks first.
The space editor is also in the menu bar, under Spaces, Edit Space, next to New Space and New Profile.
Managing profiles
Settings, Profiles lists every profile with how many spaces use it. Add, remove and rename profiles there, and set each one's search engine, archive time and download folder. "Your data and settings" opens Chromium's pages for that profile's data, and Rio's Clear Browsing Data.
The default profile and any profile a space still uses cannot be deleted, and Rio asks once before it clears a profile's site data.
For a session that leaves nothing behind, Cmd+Shift+N opens a private window.
Coming from Arc
Rio's Arc import brings your Arc profiles over with your spaces, so spaces that were on different profiles in Arc keep separate logins in Rio. See Move from Arc to Rio.
Questions
Do spaces share logins?
Spaces on the same profile share logins and favorites. Give a space its own profile and it gets its own logins, so your work accounts stay out of your personal space.
What does a profile keep separate?
History, saved passwords, logins and cookies, extensions and favorites. Each profile also has its own search engine, Today tab archive time and download folder.
Can two spaces use the same profile?
Yes. Any profile can serve one or more spaces. Settings, Profiles shows how many spaces use each one.
Can I delete a profile?
Yes, unless it is the default profile or a space still uses it. Rio asks once before it clears the profile's site data.
