Do Browser Profiles Work for Signal? Keeping Two Accounts Apart on One PC

Do browser profiles work for Signal? #

Not for Signal Desktop. Signal's download page (read 3 October 2026) lists apps for Android, iPhone and iPad, Mac, Windows and Linux, and mentions no browser version. It also says the desktop app needs Signal installed on your phone first. If you searched for signal desktop web, that is the answer: there is no website sign-in for a Chrome, Edge or Firefox profile to hold.

That does not make profiles useless in general. They are the right tool for web accounts, and the browser profile guide explains why. For Signal, the separation has to come from Signal's own structure, covered below.

What does a browser profile keep apart, and why does that stop short of Signal? #

What keeps two Signal accounts apart on a PC instead? #

One more fact matters here. The Help Center explains that Signal's protocol keeps state, which is why Desktop files cannot just be copied into another Signal instance, or copied again after you have linked and used the app; moving folders by hand can cause errors. It documents no way to run two Signal Desktop apps for two accounts side by side, so this guide does not describe one.

How do you hand over, back up and clean up a Signal Desktop? #

Hand over or retire a computer #

1. On your phone, open Signal Settings and go to Linked devices; on iPhone it is profile, Settings, Linked devices. Select the computer and unlink it.
2. Or, on the computer, open Settings > General > Delete Data (Mac: Signal > Settings; Windows and Linux: File > Settings). The page says you stay registered on your phone. Another Help Center page words this as Preferences > Privacy > Delete application data and notes that it deletes the data on that computer, not your account. Either way the Desktop's message history is removed, and because Desktop history cannot be moved to another device, decide first whether you need it.
3. To remove the app, uninstall it. On Windows, run Uninstall Signal.exe in C:\Users\<YourName>\AppData\Local\Programs\signal-desktop. To remove local data as well, the Backup and Restore Messages page lists C:\Users\<YourName>\AppData\Roaming\Signal; the Mac path is ~/Library/Application Support/Signal and the Linux path is ~/.config/Signal. The page tells you to replace <YourName> with your Windows user, so on a shared PC check that you are in the right user's folders before deleting anything.

Back up #

• Message history does not move between Desktops. According to the Help Center, Signal Desktop cannot move message history to or from any other device, and macOS Migration Assistant and Time Machine are not supported either.
• Desktop backups go to your Android phone. In Desktop open Settings > Backups, select Set up under Other ways to back up, choose a folder you will not rename, and store the 64-character recovery key safely. Restoring is done on the primary Android device, and restoring on iOS is not supported yet.
• Restoring removes the link. The page says a restore on the phone removes the existing link to Desktop; click the yellow banner in Desktop to relink.

What if something fails? #

• Errors after moving computers. For Chat session refreshed or out-of-sync messages, the Help Center lists: quit Desktop on the old computer, unlink it from the phone, start Desktop on the new one, link it from the phone, then uninstall and delete the old data.
• The new Desktop will not link. Confirm the latest version and fewer than five linked devices. If the network blocks it, check security software, VPN, firewall and proxy settings. More in why Signal Desktop keeps unlinking.
• You wanted a second account on the same PC. The documented route is a second number on its own phone; see two Signal accounts on one computer.

Where ADSSPEED fits #

If you came for browser profiles: Signal Desktop is not a website, so a browser profile, in Chrome or in ADSSPEED, does not hold a Signal sign-in. ADSSPEED's browser profiles each keep their own cookies, local data and browser settings, which suits web accounts. For mobile apps it offers Android phone profiles, each with its own device configuration, on Windows and macOS, with data kept on your own computer. Signal's registration rules still apply to every account. Use only accounts you own or are authorised to manage. ADSSPEED is not affiliated with Signal.
