Create multiple LINE accounts

Creating a single LINE account is straightforward. Creating many of them for outreach, customer support, or lead generation without getting flagged is a different challenge entirely.

LINE is designed for personal use, so running multiple accounts from the same device triggers the platform’s detection systems. The reliable way to do it is through Multilogin, where each account runs on its own dedicated Android cloud phone with genuine hardware identifiers including IMEI and MAC address. Every account has its own independent identity from day one, which keeps your outreach operations stable and uninterrupted.

The biggest risk with LINE accounts used for business is losing them after putting time into building contacts and chat history. This usually happens because multiple accounts share the same device signals, which the platform eventually detects and acts on.

Multilogin’s Android cloud phones prevent this by giving each account its own persistent environment. App data, chat history, and login states are all saved between sessions, so every account builds a natural usage history over time. Each cloud phone also connects through a built-in residential proxy matched to the account’s location, keeping the identity signals consistent and credible to LINE’s systems.

LINE is primarily a mobile app, and creating a new account directly on a PC is not straightforward. The most reliable method is to use a real Android environment for the registration process and then manage the account from your desktop.

Multilogin’s Android cloud phones handle this perfectly. You register the account on a genuine cloud-hosted Android device, which LINE treats exactly like a physical phone. Once the account is set up, you can manage conversations and outreach from your desktop while the cloud phone maintains the account’s mobile identity and session data in the background.

LINE is particularly popular in specific Asian markets like Japan, Thailand, and Taiwan. If you are managing accounts for clients or campaigns in these regions, each account needs to look like it is genuinely located there, not just in terms of language but in terms of its technical connection as well.

Multilogin’s cloud phones handle this automatically. Each cloud phone is assigned a built-in mobile-grade proxy with GPS settings and network signals matched to the target region. Whether you are managing accounts across multiple countries or just one, each one connects to LINE as a real local device with a consistent regional identity.

Managing LINE accounts across a team without proper infrastructure creates two problems: security risks from shared passwords and detection risks from shared devices. Both can cost you your entire account portfolio at once.

With Multilogin, each LINE account runs on its own dedicated Android cloud phone that can be assigned to specific team members with controlled permissions. No passwords are shared, and no devices are shared. Chat history and session data are stored in the cloud, so any team member can pick up a conversation exactly where it was left off without disrupting the account’s history or triggering any platform flags.

The most common reason multiple LINE accounts get blocked is simple: they share the same device. LINE’s systems look at hardware identifiers, IP addresses, and usage patterns. When these overlap across accounts, they get linked and flagged together.

The solution is one cloud phone per account. Multilogin gives each LINE account its own real Android device running in the cloud with unique hardware identifiers, a matched residential IP from a pool of 30 million addresses across 150 locations, and persistent session data that builds natural usage history over time. Each account is completely isolated, so a problem with one never affects the others.
