Using more than one account for the same app is now a normal part of work and everyday life. You might have separate Gmail accounts for work and personal messages, multiple Slack workspaces, several social media profiles, or different accounts for each client you manage.
To use them at the same time without logging out, each account needs its own login session. Some apps have a built-in account switcher. Otherwise, you can use private windows, separate browsers, or browser profiles, or a multi-account manager such as WebCatalog Desktop, which keeps each account in its own persistent profile so it stays signed in.
Why one browser gets in the way
Most web apps remember one signed-in account per browser through cookies. Sign in to a second account in the same browser and you often replace the first session, which means more passwords, more two-factor codes, and a higher chance of sending a message from the wrong account. The fix is to keep each account’s session separate.
Common ways to use multiple accounts
1. Use the app’s built-in account switcher
Some services let you add several accounts and switch between them from inside the app. Google’s account menu, for example, keeps several accounts signed in at once (see how to manage multiple Gmail accounts), and Slack lets you switch between workspaces you are signed in to (see how to manage multiple Slack accounts).
This is convenient when it is available, but it does not always let you work in two accounts side by side. Support also varies between apps, and notifications from different accounts can become difficult to distinguish.
2. Open an incognito or private window
A private window creates a temporary session separate from your main browser window. You can use it to sign in to a second account without signing out of the first one.
However, the session usually disappears when you close the private window. You may need to sign in and complete two-factor authentication again the next time you open it. Private browsing works well for temporary access, but it is not ideal for accounts you use every day.
3. Use different browsers
You could keep one account in Chrome, another in Firefox, and a third in Edge.
This creates separate sessions, but it becomes difficult to manage as the number of accounts grows. Your apps, bookmarks, extensions, and notifications also become scattered across multiple browsers.
4. Create separate browser profiles
Browser profiles keep cookies and login sessions separate. For example, you might create one Chrome profile for work and another for personal use.
This is a practical option when you only have a few broad identities. However, switching entire browser profiles can feel excessive when you simply want to open a second Gmail, Slack, or WhatsApp account.
5. Use a multi-account manager such as WebCatalog Desktop
WebCatalog Desktop turns web apps into desktop apps that open in their own window with a Dock or taskbar icon. Its profiles keep cookies, sessions, and browsing data separate, so several accounts of the same app can stay signed in at once.
- Download WebCatalog Desktop for macOS, Windows, or Linux, and add the apps you use.
- Open WebCatalog Desktop and go to Profiles.
- Select Add profile, then give it a recognizable name, such as “Work” or “Client A.”
- Open the app with that profile and sign in to the matching account.
- Repeat for each additional account.
You sign in once per profile, and the account stays available the next time you open it. A profile can be reused across apps, so a Client A profile can hold that client’s Gmail, Slack, and other logins. The profile help article covers editing and removing profiles.
Organize related accounts with spaces
If you manage several apps as well as several accounts, spaces group them by client, project, business, or area of your life. Each space opens in its own window and can have subspaces.
For example, an agency could create:
- Client A space: Gmail, Slack, Instagram, and Shopify, each opened with the Client A profile
- Client B space: Gmail, Microsoft Teams, LinkedIn, and an analytics dashboard, each opened with the Client B profile
You can then open the right space instead of searching through unrelated apps. Spaces handle the organization; the profiles are what keep each client’s logins separate.
Practical tips for managing multiple accounts safely
Use clear profile names
Avoid names such as “Account 1” and “Account 2” when possible. Use labels that immediately identify the purpose, client, region, or organization connected to the account.
Make accounts visually distinct
Assign different colors, icons, or profile images to accounts with similar interfaces. Visual differences are especially useful when you have several windows open together.
Check the active account before publishing
Before sending an email, publishing a post, changing an ad campaign, or updating store settings, confirm which account is active.
Separate sessions reduce account mix-ups, but they cannot prevent every human error.
Protect sensitive accounts
Use unique passwords and enable two-factor authentication wherever possible. If other people can access your computer, lock your screen when you step away.
Follow each service’s account policies
Session separation is designed to make legitimate multi-account workflows easier. It does not override the rules of the websites you use.
Some platforms limit how many accounts a person may operate or restrict certain kinds of automation and commercial activity. Always review the relevant platform policies.
Multiple accounts without constant account switching
Use an app’s own account switcher when it covers what you need. For accounts you open every day, give each one its own persistent session: download WebCatalog Desktop and create a profile for each account.
