Still, some might find it hard to manage due to certain capacity and message limits. Simply put, since WhatsApp applies an authentication system that uniquely connects it to one phone number, it is challenging to access the WhatsApp account on multiple devices at the same time. This is exceptionally challenging for medium and large businesses, with thousands of inbound messages and countless users, how can they keep track of all communications with only one device?

This is especially true for businesses that use WhatsApp links that make it even easier for customers to contact them, leading to a surge in conversations. Such businesses may then choose to use a WhatsApp Manager to better manage conversations!

WhatsApp Business Multi-Device VS Multi-User

WhatsApp Business App users can log in to their account on mobile phones, tablets and laptops via WhatsApp Web. In other words, logging in to the same WhatsApp Business Account using multiple devices can be done easily.

However, when it comes to multiple users sharing the same account, it is another story. One account can be linked to one phone at a time so it is nearly impossible for multiple users to manage the same account using multiple phones. If it is a problem you have been facing, you would need to look into another solution - WhatsApp Business API.

How to use WhatsApp Business on multiple devices?

You can use WhatsApp on up to four linked devices at once without the need to keep your phone connected. However, you can only have one phone linked at a time.


  1. Open WhatsApp on your phone.

  2. Tap More options > Linked devices.


  4. Unlock your phone:

    • If your device has biometric authentication, follow the on-screen instructions.

    • If you don’t have biometric authentication enabled, you’ll be prompted to enter the pin you use to unlock your phone.

  5. Point your phone at the screen of the device you want to link to scan the QR code


  1. Open WhatsApp on your phone.

  2. Go to WhatsApp Settings.

  3. Tap Linked Devices.

  4. Tap Link a Device.

  5. Unlock your phone if you’re on iOS 14 or above:

    • Use Touch ID or Face ID to unlock.

    • If you don’t have biometric authentication enabled, you’ll be prompted to enter the pin you use to unlock your phone.

  6. Point your phone at the screen of the device you want to link to scan the QR code.

How to set up a multi-user login on WhatsApp Business?

As we just said, WhatsApp’s #1 position in the global messenger apps ranking list is well-earned. In August 2018, Facebook announced the launch of WhatsApp Business API, making it practical for brands to manage large volumes of messaging inquiries.

What is WhatsApp Business API?

Through the WhatsApp Business API, businesses can finally integrate WhatsApp with Customer Relationship Management (CRM) software, saving them from a lot of hassle, while boosting team productivity and streamlining communications with different stakeholders.

Adding WhatsApp to a CRM system unlocks many add-ons. For example, the whole team will be able to view and respond to messages received through WhatsApp together as the app is no longer limited to a single phone and user. Moreover, if a potential customer messages you for the first time, a lead card will be created and saved to the system. Once a lead already has an assigned responsible service agent, he or she will be the only one to be notified, thus, the rest of the team won’t get distracted.

In short, the WhatsApp Business API can greatly enhance workflow efficiency by allowing integrations with your own systems, helping the team to unleash the full potential of WhatsApp as a channel for communication with customers.


How you can use WhatsApp Business API depends on your service provider. SleekFlow offers an Android version for users to download from Google Play.

An iOS version is also available for iPhone users. Go to App Store and download the application. Once the installation is finished, you can log in to your SleekFlow account and message your customers.

In order to improve operational performance, multi-staff access feature is available. With SleekFlow, you can quickly and easily add users to your platform and organize them into teams. When a new conversation comes in from a new customer, it will be set as unassigned. As soon as one of the teammates replies, he or she will automatically take the conversation, any new notifications from such conversation will therefore only be visible to that person. In the following tab, members can see all the conversations assigned to them.


These basic functions help to boost customer support efficiency and cross-functional collaboration across teams. You can also use the automation workflows to segment contacts and allocate inquiries to specific staff. By making the bots handle all the fuss, businesses can now focus on providing better and faster assistance at various touchpoints of the customer journey.
