Several accounts of the same service on one PC
A personal account and a work account on the same site, and you have to sign out of one to see the other. It is a daily friction for anyone straddling two digital lives, and the cause is always the same.
The mechanism, once and for all
A browser files a site’s data (cookies, local storage, local databases) in a single space identified by the domain. That space is isolated from other sites, but it is not subdivided by account. Sign in a second time to the same domain and the new session takes the old one’s place: there is one drawer, and it holds one set of keys.
Some services work around the limit themselves by handling several identities server-side. The rest never had a reason to. The result is an uneven landscape, and it is worth knowing before you go looking for a tool.
Which services are genuinely affected
| Service | Several accounts at once in a browser | Detail |
|---|---|---|
| WhatsApp Web | No | One session per browser; the second signs the first one out |
| Microsoft Teams | No | Microsoft’s own answer is to use a different browser or a private window |
| Discord | No | One account at a time; no account switcher in the client |
| Outlook on the web | Partly | Work and personal accounts frequently conflict in the same window |
| Gmail | Yes | Google supports up to ten simultaneously signed-in accounts |
| Telegram | Yes | The desktop app handles several accounts natively |
| Messenger | Yes | Multi-account has been supported since 2024 |
Half of this table is not a problem at all, and saying so matters: if your need stops at Gmail or Telegram, you do not need any extra tool. Only the first half is the subject here.
The workarounds, and where they stop
- A private window works, but it is built to remember nothing: closing it wipes the session, and you start over.
- A second browser works too, at the price of two applications open all day, twice the memory, and notifications split between them.
- Browser profiles are the clean answer on the browser’s own terms, but switching swaps the entire context at once: tabs, extensions, bookmarks, history.
- Container extensions isolate sessions well, but they remain extensions: tied to one browser, to an API that shifts, and offering neither system notifications nor dedicated shortcuts.
None of these is wrong. They all work. They simply ask for a small daily manoeuvre that you end up paying for in attention.
What an isolated session does
In practice: accounts stay connected in parallel, including after a restart; each has its own unread badge and mute setting; and you move between them with a click or Ctrl+1 to Ctrl+9, with nothing to reload.
Where to start
The three most commonly affected services each have their own page, with the steps and an honest comparison of the alternatives. If your need lies elsewhere the principle is unchanged: any URL can be added as a service in its own right.
Common questions
- Is this the same as Chrome profiles?
- The isolation is comparable, the experience is not. A Chrome profile separates a whole browsing environment and opens in its own window. Nexus separates service by service inside one window: two WhatsApp and two Teams accounts coexist without four windows to manage.
- Is there any risk to my accounts?
- Nexus loads the official web interfaces without modifying them, without sitting between you and the service, and without automating anything. Each service sees an ordinary web session. Data stays local to your machine.
- How many accounts can stay open?
- The application sets no limit. Each service uses memory much as a tab would; per-service sleep returns that memory to Windows while you are not using it.
- What if my service is not in the catalogue?
- Any web address can be added as a service with its own isolated session. The catalogue only pre-fills the common ones with their logos.
