LINE BITMAX Help Center

As mentioned in our notice about resetting your passcode, you need to set a new six-digit passcode to use LINE BITMAX.
Note: If you haven't set a new passcode, you'll be shown instructions to do so when you access LINE BITMAX service screens.

If you haven't set a new passcode by 11 am on April 23, 2025, some transactions and features will be restricted. Please verify your identity from the pop-up instructing you to do so that's shown when you try to use a restricted transaction or feature.

Transactions and features subject to being restricted:
• Adding a new bank account
• Viewing/changing your personal information
• Viewing/changing your registered information
• Opening a margin trading account
• Deleting your LINE BITMAX account
• Trading on the brokerage (In principle, per day amounts of JPY 100,000 and greater in transactions are subject to restriction. If you opted to add passcode verification, per day amounts under JPY 100,000 in transactions are also included.)
• Trigger orders on the brokerage
• Trading on the exchange
• Margin trading (margin sell and closing buy trades)
• Withdrawing Japanese yen
• Receiving crypto assets
• Sending crypto assets
• Submitting new lending applications for the Crypto Asset Lending Service
• Changing your passcode and adding passcode verification for certain transactions and features
• Issuing trade reports (if you've opted to add passcode verification for it)

To remove the restrictions:
• You need to verify your identity with your My Number Card.
Note: Your identity cannot be verified with a form of ID other than your My Number Card.　If you don't have a My Number Card, you can verify your identity after acquiring one.
• Please verify your identity by tapping Verify on the pop-up shown when you try to use a restricted transaction or feature. For more information about how to verify your identity, see the following LINE BITMAX official blog content. (Only available in Japanese.)
