What is Zalo Web
Zalo Web is the browser-based version of the Zalo messenger. It allows users to log into their accounts on a computer without installing the app. After logging in, the main features of the platform are available directly in the browser. This can be useful when you need quick access to your chats on a computer, when sharing files, or when logging into an account from someone else’s device.
Official Zalo Web address
To log into Zalo Web, use the official page at id.zalo.me.
Before logging in, check the website address again and make sure the connection is secure: it should use HTTPS.
How to log into Zalo Web on a computer
The messenger offers two ways to log into its web version: by using a QR code or a password.
Logging in with a QR code
This method also requires the Zalo app on a smartphone. Open the Zalo Web page, and a QR code will appear on the screen.
Step-by-step instructions for logging into Zalo Web with a QR code:
Open Zalo Web in a browser. The QR code will appear immediately.
Open the Zalo app on a smartphone.
Open the QR code scanning feature in the app.
Scan the code with the camera.
Check the account details and confirm the login.
The account will then open in the browser.
Logging in with a phone number and password
To use this login method:
On the Zalo Web home page, click the settings button (three horizontal lines) to the right of Login with QR code.
Select Login with password.
In the window that appears, enter the phone number associated with the account.
Enter the password.
Click Login.
Complete an additional verification step if requested by the service.
Confirm the login.
Main features of Zalo Web
With Zalo Web, you can:
send, receive, and forward text messages in personal and group chats;
view chat history synchronized between your phone and computer;
attach, view, and download photos, videos, and files;
make voice and video calls;
search for messages within chats, as well as users by name or phone number;
manage notifications for individual chats.
Advantages of Zalo Web
No app installation required. Zalo Web works directly in a browser, so you can quickly open the messenger on a computer and upload or download large files.
Quick access to the account. After the first login, signing in again takes minimal time—simply open a new browser tab with Zalo Web.
Suitable for temporary use. Zalo Web is also convenient to use on an office or someone else’s computer. Afterward, simply log out of the account.
Disadvantages of Zalo Web
Zalo Web allows you to use the messenger in a browser, but a mobile app is still required in some cases. In addition, the web version has some technical limitations. Let’s take a closer look:
Creating a new account is not possible. Zalo Web only allows you to log into an existing account. A mobile app is required to register a new account.
Not all settings are available in the web version of Zalo. For example, privacy settings cannot be changed and backups cannot be enabled here.
Some features are only available in the mobile app. For example, the web version of Zalo does not include “Diaries” or “Moments,” a feature similar to Stories.
Can’t log into Zalo Web?
In its official documentation, Zalo lists common errors that can occur when logging into an account on a computer, including when using a QR code. Here are the main ones:
Incorrect account credentials
Check the phone number and password. Make sure the credentials belong to the account being accessed.
Error 2028: unable to log in on a computer
Error 2028 occurs when it is not possible to log into Zalo Web on a desktop or laptop. In this case, Zalo recommends changing the password or trying to log in again.
QR code not working
If the Zalo app on a smartphone does not recognize the QR code, check the app version and update it to the latest version if necessary. Then reopen the QR code in the browser and try scanning it again.
Error 2020: account blocked
Error 2020 means that access to your Zalo account has been temporarily restricted. This may happen due to a violation of the platform’s rules. To find out the reason and how to restore access, contact Zalo Support.
Internet connection issues
The error may occur because the Internet connection is unstable or unavailable. When logging in with a QR code, make sure both the computer and smartphone are connected to the Internet.
Errors 502, 647, and 2017: incorrect date and time
Errors 502, 647, and 2017 may appear if the date and time on the computer do not match the data in the app. Enable automatic date, time, and time zone settings. Then try logging in again.
Temporary service outage
Sometimes the issue is on the messenger’s side. If the browser, Internet connection, and device are working normally but you still can’t log into Zalo Web, wait and try again later.
Outdated browser
An outdated browser may prevent Zalo Web from loading or interfere with account login. Update Chrome, Opera, Safari, Firefox, or another browser that you use to its latest version. Then try logging into Zalo Web again.
Zalo Web vs. Zalo PC vs. Zalo mobile app: how to choose
In addition to Zalo Web and the Zalo mobile app, the messenger is available as the Zalo PC app for desktops and laptops. These three options are suitable for different use cases.
Zalo Web | Zalo PC app | Zalo mobile app | |
How it works | In a browser | As an app | As an app |
App installation | Not required | Required | Required |
Chats and messages | Available | Available | Available |
Photos, videos, and files | Available | Available | Available |
“Diaries” and “Moments” | Not available | Not available | Available |
What to choose
Zalo Web: a good option when you need quick access to the messenger in a browser without installing an app.
Zalo PC: suitable for regular use on a desktop. The desktop version offers additional settings and tools, including file storage folder management, keyboard shortcuts, and notification settings.
Zalo mobile app: the main option for smartphones. The app provides the most complete set of features, including those not available in Zalo’s web and desktop versions.
How to use Zalo Web with multiple Zalo accounts
Zalo does not prohibit having multiple accounts, but it does limit their number without specifying the limit exactly. For example, one personal account and several work accounts can be used for different clients or projects. Each account needs to be registered to a separate phone number, so multiple accounts require different phone numbers.
When working with multiple Zalo accounts, constantly logging out of one account and logging into another can be inconvenient. An anti-detect browser such as Octo Browser can greatly simplify this process.
How to manage multiple Zalo accounts in an anti-detect browser
First, register the accounts in the Zalo mobile app. Then, create a separate Octo Browser profile for each account and log into Zalo Web accounts. As a result, each Zalo account will operate in its own isolated environment.
After the first login, there is no need to enter the login credentials again each time. Log into the required accounts once, then simply select the desired profile from the list and launch it to switch between Zalo accounts.
Octo Browser comes with its own built-in Proxy Shop offering verified residential and mobile IP addresses. We recommend connecting a separate proxy to each profile to reduce the risk of blocks when working with multiple accounts.
