Can FlashID manage multiple Line accounts?

Yes. FlashID creates isolated environments with unique device fingerprints and dedicated IP addresses for each Line account. This prevents Line's sophisticated detection systems from associating your accounts. While Line's policies limit the number of personal accounts, business use cases (such as agency management) benefit from FlashID's ability to maintain independence between accounts.

Do unique credentials need to be used for multi-opening Line via FlashID?

Absolutely. Each Line account must have its unique credentials, including email address, phone number, and personal information. FlashID ensures that these credentials remain isolated in separate environments, preventing Line's algorithms from detecting connections. Never reuse phone numbers or emails across accounts, as this will trigger Line's security systems, no matter the fingerprint isolation.

How to switch between multiple Line accounts?

1. Native Line switch: Open the app → Tap the menu icon → Scroll down and tap your profile → Select 'Add Account' → Enter credentials (this leaves account association traces).
2. FlashID switch: Each account operates in its isolated environment—simply click between windows to instantly switch accounts without leaving connection footprints or logging out, significantly reducing detection risks.

Will multi-opening Line via FlashID lead to account restrictions?

Risk is minimized with proper use. FlashID's unique device fingerprints and IP isolation drastically reduce detection chances, but Line actively enforces policies against spam, fake accounts, and automation. Restrictions typically arise from account behavior violations rather than multi-account management itself. Maintaining authentic activity patterns and following platform guidelines ensures account safety.

What should be noted when multi-opening Line via FlashID?

1. Authentic identities: Ensure each account has unique, realistic information, including appropriate profile pictures and activity history.
2. Unique identifiers: Use distinct email addresses, phone numbers, and avoid cross-referencing accounts.
3. Natural activity patterns: Avoid identical posting schedules or content across accounts.
4. Gradual account warming: New accounts should start with minimal activity and gradually increase over 2-3 weeks.
5. Avoid automation: While FlashID supports automation, maintain human-like patterns and avoid excessive actions in short time frames.

How to recover a temporarily locked Line account?

1. Identity verification: Follow Line's on-screen instructions which generally involve confirming your identity through uploaded ID documentation.
2. Security checks: Complete any necessary security verifications including email confirmation or SMS codes.
3. Appeal process: If standard recovery does not work, use Line's appeal form to explain your situation.
4. Prevention with FlashID: Utilizing FlashID's isolated environments significantly reduces the risk of temporary locks by preventing suspicious login patterns that trigger Line's security systems.

What's the difference between Line account deactivation and deletion?

1. Deactivation: Temporarily hides your profile and content from other users. Your information is still stored, and you can reactivate at any time by logging back in. Friends, photos, and timeline will remain intact but invisible until reactivation.
2. Deletion: Permanently removes all your data after a 30-day grace period (during which you can cancel the deletion). After this period, you cannot recover any content, and you would need to create a brand-new account to return to Line.

How much storage space do Line free users have?

Line provides unlimited storage for standard messages, photos, and videos for free users. However, there are file size limitations: photos may be compressed, and videos are typically capped at 4GB per upload with maximum length restrictions. Line's storage is independent of device storage and does not count against any personal cloud storage quotas.

What's the difference between FlashID and regular browsers for multi-opening Line?

Regular browsers share device fingerprints, cookies, and often IP addresses, allowing Line's algorithms to easily identify account connections, often resulting in restrictions for suspicious activity.
FlashID creates entirely isolated environments for each account: unique browser fingerprints, dedicated IP addresses, and separate cookies/cache data. This effectively simulates different physical devices accessing Line independently, greatly reducing association risks and safeguarding your accounts from cross-detection.

Can Line track multiple accounts on the same device?

Yes, Line possesses sophisticated tracking abilities that can identify multiple accounts utilized on the same device through browser fingerprinting, cookie tracking, IP address scrutiny, and device identification. FlashID specifically counters these tracking methods by establishing fully isolated environments with unique fingerprints, preventing Line from linking your accounts even when accessed from the same physical computer.
