One browser.
Every account, at once.
Multi-Login Manager keeps separate, isolated login sessions for the same website — so you stop logging out just to log back in as someone else.
Three steps. No account. No cloud.
Everything runs locally, the moment you install it.
Create a profile
Name it, pick a color, give it an icon. Takes ten seconds.
Log in inside it
Its cookies and local storage stay isolated from every other profile.
Switch instantly
New tab, new window, or swap a tab's session in place — your call.
Real isolation, not a party trick
Chrome gives extensions no native "multiple identities" API — so this one builds the closest thing that actually works, and documents exactly where the platform draws the line.
Cookies and local storage, actually separated
Each profile's session is snapshotted and swapped automatically as you navigate or switch tabs — not just hidden behind a UI, genuinely kept apart.
See who's tabbed in, at a glance
Profiles sharing one window get their own colored, labeled tab group — in Chrome's actual tab strip, not a custom overlay.
Change a tab's profile in place
No new window, no new tab — swap the active session and reload, or jump straight to any profile with ⌘K.
Log in first, organize later
Sign into a site in a plain tab and the extension notices — one click adopts that already-logged-in session into a new profile.
The smaller stuff that makes it usable day to day
Search, groups & favorites
Find a profile fast once you have more than a handful — group, tag, and pin the ones you use daily.
Duplicate a profile
Clone an existing profile's setup instead of building a new one from scratch.
Import & export
Back up every profile to a file, or move them to another machine — validated on the way back in.
Context menu & shortcuts
Right-click a link to open it in a specific profile, or drive the whole thing from the keyboard.
Full dashboard
The popup covers quick switches; a dedicated tab handles everything else about managing profiles.
Light, dark & system theme
The extension itself follows your OS setting, or you can pin it to one or the other.
Session management. Not disguise.

Local by design
No account, no backend, no sync service — nothing this extension does requires a network request to anywhere we control.
If you juggle accounts, this is for you
Agencies & freelancers
One login per client, never mixed up.
E-commerce sellers
Run multiple storefronts without signing out.
Social & community managers
Personal and brand accounts, side by side.
QA & developers
Test as three user roles without three browsers.
Versus doing this manually
Incognito windows and Chrome's built-in profiles are the usual workarounds. Here's how they actually hold up.
| Capability | Incognito windows | Chrome profiles | Multi-Login Manager |
|---|---|---|---|
| Multiple accounts, same window | No | No | Yes |
| Colored tab groups per account | No | No | Yes |
| Switch accounts without reopening | No | No | Yes |
| Session persists after closing | No | Yes | Yes |
| Setup per account | none | full new profile | one click |
Before you install
Does this sync across devices or need an account?
What happens to my profiles if I uninstall it?
Will it slow down my browser?
Does it hide me from fingerprinting or bypass CAPTCHAs?
Is every part of a site isolated between profiles?
