Link your login methods, enable Two-Factor Authentication and balance alerts

Link third-party logins (optional)

If the site supports it (GitHub / LinuxDo / WeChat / Google, etc.), we recommend linking at least one:

• Benefit: an extra login path if you forget your password
• How to: Profile → Login methods → Link the corresponding platform account

Enable Two-Factor Authentication (2FA)

We strongly recommend enabling it to prevent account theft if your password is leaked:

1. Profile → Security settings → Enable Two-Factor Authentication
2. Scan the QR code with a phone authenticator app (Google Authenticator / Microsoft Authenticator / 1Password, etc.)
3. Enter the 6-digit code from the authenticator app to complete the setup
4. Save the recovery code (offered by some sites) so you can recover access if you lose your phone

WARNING

• Once 2FA is on, every login requires a dynamic code
• Be sure to save the recovery code/backup key; otherwise, if you lose your phone you won't be able to log in and will have to contact support (support@kuaiapi.net) to reset it

Balance reminders

Once enabled, a reminder is sent (by email or another method) when your balance falls below the threshold you set:

1. Profile → Notification settings
2. Turn on "Low balance reminder"
3. Set the threshold (for example $2)
4. Confirm the reminder email address is correct

Benefit: it helps you avoid service interruptions caused by an exhausted balance, especially when automated tasks are running.

Account quota reminders

Some sites also support a "low account quota reminder" (a notification when a channel account's quota is nearly used up). Leaving it on helps you head off problems early.
