Ethereum (ETH) remains one of the most widely traded cryptocurrencies in the world, attracting both new and experienced investors. Whether you're looking to buy ETH with Japanese yen, exchange Bitcoin (BTC) for Ethereum, or simply manage your digital asset portfolio, understanding how to navigate a secure trading platform is essential. This guide walks you through the process of trading Ethereum safely, managing account security settings, and resolving common access issues—without compromising on user experience or safety.
How to Start Trading Ethereum
Once your identity verification is complete, you can begin trading Ethereum immediately through either the Ethereum sales desk or the bitFlyer Lightning interface. On the bitFlyer Lightning screen, simply click on “ETH/BTC” or “ETH/JPY” located at the top of the page to access real-time trading options.
The Ethereum sales desk allows direct purchases of ETH using Japanese yen (JPY), making it ideal for beginners who want a straightforward entry into the crypto market. Meanwhile, the ETH/BTC pair enables advanced users to swap between Bitcoin and Ethereum based on market movements and investment strategies.
For those preferring fiat currency trading, ETH/JPY offers full buy/sell functionality using yen, ensuring liquidity and ease of use for Japanese residents.

Managing Two-Factor Authentication (2FA)
Security is paramount when dealing with digital assets. Two-factor authentication (2FA) adds an extra layer of protection to your account. If you're logged in and wish to modify or disable your 2FA settings, follow these steps:
- Log in to your account.
- Navigate to the Settings menu.
- Select Security Settings to adjust your 2FA preferences.
However, if you're unable to log in due to lost access to your authentication method, don’t worry—support is available.
If You Can’t Log In
After completing identity verification, you may request a 2FA reset. Submit your request via the official form provided by the exchange.
🔍 Important Notes After 2FA Reset:
Even after disabling two-factor authentication, the platform continues to send verification codes via email as part of its enhanced security protocol. If you’re not receiving emails, check the following:
- Ensure that
@bitflyer.comand@bitflyer.jpare added to your email’s allowed sender list. - Review your email filtering settings to confirm our domain isn’t blocked.
- Check your spam or junk folder—emails may have been redirected there automatically.
If these steps don’t resolve the issue, proceed to contact customer support directly.

Recovering Lost Passwords
Forgetting your password is common—but easily fixable. If you're unable to log in because of a forgotten password:
- Visit the password reset page.
- Enter your registered email address.
- Click on “Request password reset for bitFlyer.”
- Follow the instructions sent to your inbox.
Special Cases: SMS Issues
If you’ve changed your phone number or never registered one, and therefore cannot receive SMS codes:
- Use the dedicated recovery option labeled “Can’t receive SMS?”
- To protect your assets, identity verification documents will be required.
- In some cases, a verification call from the support team may also be necessary.
This additional step ensures only authorized individuals regain access to sensitive accounts.
Changing Your Registered Email Address
Due to strict security policies, users cannot change their login-related information—including email addresses—directly from their account dashboard. Instead, all changes must be processed manually through customer support.
If You Can Log In
- Open the contact form.
- Choose the category: Update Registered Information.
- Fill in your full name and current email.
- Select Email Address as the information you'd like to change.
- Provide the new email address and submit.
If You Cannot Log In
Follow the same process but select Other as the change type, clearly stating that you'd like to update your email address.
After submission, a confirmation message will be sent to your new email. You must reply accordingly to initiate verification.
A valid government-issued ID will be required to confirm your identity. Depending on your account status, a support agent might call you directly for additional verification.
We understand this process may seem time-consuming, but it's designed to safeguard your digital assets against unauthorized access.
Frequently Asked Questions (FAQ)

A: While possible under certain conditions, disabling 2FA reduces account security. We recommend keeping it enabled and using authenticator apps instead of SMS where possible.
