How to Sync QQ Between Devices

One of QQ's best features is that a single account works everywhere at once. Here is how to run QQ on your PC, Mac and phone with everything kept in sync.

How QQ Sync Works

Your QQ identity — your QQ number, contacts and recent message history — lives in the cloud, tied to your account rather than to any one device. When you sign in on a new device, QQ downloads that account data, so your contact list and conversations are there instantly. Send a message from your laptop and it appears on your phone moments later.

Step-by-Step: Sync QQ Across Devices

1

Install QQ on each device

Download and install the official QQ app on every device you want to use — Windows, Mac, Android, iPhone or Linux.

2

Sign in with the same QQ number

On every device, sign in using the same QQ number and password. This is what links them to one synced account.

3

Confirm the login

QQ may ask you to confirm a new device login from a device you already trust, as a security step. Approve it to finish connecting.

4

Let your data sync

Your contacts and recent chats download automatically. Give it a moment on first sign-in, especially for large contact lists.

5

Set per-device preferences once

Configure local options — notifications, scan settings — on each device, since some preferences are stored locally rather than synced.

Tip: if you plan to reinstall or move computers, see how to back up your QQ vault so you keep local cached files too.
FAQ

FAQ: Syncing QQ Between Devices

Can I use QQ on multiple devices at the same time?

Yes. QQ supports being signed in on a desktop and a mobile device at the same time. Messages and contacts stay in sync, so you can start a conversation on your phone and continue it on your computer.

How does QQ keep my chats in sync across devices?

Your account, contacts and recent messages are tied to your QQ number in the cloud. When you sign in on another device, QQ pulls that account data down, so your contact list and ongoing chats appear automatically.

Do per-device settings sync too?

Account-level data syncs, but some preferences are stored per device. Settings like scan options or local notifications may need to be configured once on each device, while your identity and contacts always follow your QQ number.
