How to Login to Zalo on Multiple Devices: Maybe You Don't Know?
Zalo is known as a popular method of communication among Vietnamese people, but when introduced into the business environment, many limitations begin to appear. In particular, the limit on logging in on multiple devices makes it difficult to manage or switch between accounts. So how many devices can Zalo log in on? How to use multiple accounts at the same time safely and effectively? Join SaleSmartly to find out details in this article.
How many devices does Zalo allow users to log in to?
A Zalo account can only be used stably on one phone device, one PC application and one Zalo web browser. If you continue to log in on another device, your account will automatically log out of the old device, interrupting the ongoing conversation and sometimes not synchronizing old messages. This causes limitations when dividing accounts among the customer service team when there are many personnel.
## Does Zalo allow logging into 1 account on 2 phones at the same time?
The answer is no. Zalo does not allow logging in to 1 account on 2 phones at the same time (using the app). When you log in to your account on a second phone, the first device will be logged out to protect user data. However, you can still use the app on the first phone and log in to the browser on the second device. If your business needs multiple employees to process messages on Zalo, you should choose a conversation management software solution to decentralize authority instead of sharing a Zalo account on multiple devices.## What problems does logging into Zalo on multiple devices cause?
The customer service team shares the same Zalo account and logs in on many different devices, which may cause the following limitations:
- Account security
If you log back in too many times on your browser or change devices continuously, Zalo may also request re-verification to ensure security, causing inconvenience to the processing process.
- Difficulty in managing customer lists
Customer management ability is also a big issue. When messages pour into a Zalo channel, it is difficult for employees to classify and easily miss messages, leading to slow responses as well as missing customers. On the other hand, if a business uses many other Zalo accounts, it also makes it difficult to control the number of customers, the business needs to review each account and synthesize them manually.
- Measurement and statistical processes are not optimal
Manual management makes it difficult for businesses to measure the number of messages answered, response time, return rate or backlog of conversations.. This makes the process of optimizing customer service more time-consuming and difficult to optimize.
- Data control risks
Security is also a potential risk when many people hold the same Zalo account, businesses cannot control who is viewing the data, and may lose customer information or chat history. The worst case scenario is when an employee quits, revealing account information as well as customer data.
