A supplier sends an updated quotation through Zalo. A client asks whether the delivery date is confirmed. Your family group is discussing weekend plans. When these conversations belong to different accounts, finding the right chat is only part of the work. You also need the correct document, the latest decision, and a clear next step.
On your phone, Zalo's own account switcher may be all you need. On a computer, Zalo PC and Zalo Web each keep one account signed in, so two accounts usually means one in the desktop app and one in a browser. To keep several accounts open at once, each in its own window, give each account a separate profile in WebCatalog Desktop and place the work account beside your documents, calendar, and tracking tools.
This guide follows a practical example: a project coordinator working with a Vietnamese supplier while keeping personal conversations in another account.
Give each Zalo account a stable home
First, decide which conversations actually belong to different identities. A personal account and an established work account may need separate sessions. Several customers talking to the same work identity can remain in that account; a new project does not automatically require another login.
Zalo already offers Windows and Mac applications, mobile apps, and a web version. Recent versions of the mobile app let you add a second account and switch between them from the app's settings (Chuyển tài khoản), which works well if you check one account at a time. On a computer, using Zalo PC for one account and Zalo Web in a browser for another is the native arrangement. WebCatalog Desktop is useful when you want both accounts in their own windows with Dock or taskbar icons, named by purpose, next to the web apps around your conversations.
For two Zalo accounts on PC or Mac, start with the accounts you already use and can authenticate. Install WebCatalog Desktop, add Zalo from its app catalog, then:
- Open Profiles, choose Add profile, and name the first profile “Zalo Work.”
- Open Zalo with that profile and sign into the intended work account.
- Add another profile named “Zalo Personal.”
- Open Zalo with the Personal profile and sign into your other account.
- Check the account identity and expected conversations in each window before replying.
WebCatalog's profile documentation explains that profiles keep cookies, sessions, and browsing data separate. Opening another window with the same profile reuses that session; select the other profile when you need the other account.
For QR authentication, Zalo's official sign-in instructions say to display the code on the computer, scan it with Zalo on your phone, review the login information, and confirm. Make sure the phone is using the account intended for that desktop profile. Labeling a profile “Work” cannot change which account approved the sign-in.
When opening the service directly, use Zalo Web, the web chat address identified by Zalo Help. If Zalo later asks you to authenticate again, complete its normal sign-in process in the appropriate profile.
Put the work around the conversation
An account window is a useful starting point. A working context also needs somewhere to check facts and record decisions.
Create a “Supplier Projects” space in WebCatalog Desktop. Add Zalo using the Work profile, your document app, an order tracker, and the calendar used for delivery commitments. A space groups the apps and bookmarks for a purpose in its own window.
Keep the roles clear: the profile selects the signed-in session; the space groups the tools. You can reuse the same work profile across project spaces when the projects share a Zalo identity. Another space by itself does not create a different account or limit that account to a particular customer.
Start with one work space and a separate personal Zalo window. Add something because it helps you finish a task, such as checking a quotation or confirming a meeting.
When customer replies belong to a team, use Zalo Official Account roles
Zalo Official Account, or Zalo OA, solves a different problem from keeping two personal logins open. It gives a business a customer-facing account that several staff members can manage. According to Zalo's Official Account getting-started guide, staff sign into OA Manager with their own personal Zalo accounts, and an administrator invites them through Quản lý → Quản lý admin with the permissions they need.
If you manage several OAs, choose the right one inside OA Manager; you don't need a separate profile for each. Zalo OA also offers conversation assignment, depending on the OA plan and staff permissions. Choose OA roles when the need is shared customer ownership, and separate profiles when the need is separate signed-in identities.
Check the details that affect your daily work
Before moving your routine into a new desktop arrangement, try one representative conversation from start to finish. Can you open the message you need, inspect its document, send the intended reply, and record the follow-up? If calls are part of that workflow, check them in the actual environment you intend to use. Zalo's native and web experiences can have different capabilities.
Review notifications in each account and your desktop settings. The work account should draw attention to conversations you are responsible for, while personal alerts can follow your preferred work hours. Confirm that expected alerts arrive before relying on the arrangement for time-sensitive replies.
Check important history and files separately. Zalo provides backup and restoration guidance for changing phones, and its own processes govern what is available after a device or session change. A WebCatalog profile is not a backup of your Zalo message history. Keep essential project records in the location your team has chosen for them.
Start with your next real conversation
Choose one work account, one personal account, and one project that regularly produces Zalo messages. Download WebCatalog Desktop, give each Zalo login a named profile, and place the work session beside the documents and tracker needed for that project.
