pixiv takes measures against unauthorized access to accounts on our services.
We take a multi-pronged approach to security. If we detect that a third party may have attempted to access an account without permission, we send an e-mail to the user. We also prevent the use of passwords that may be easily guessed by third parties, and take measures against cyberattacks that use software to generate multiple login attempts.
We also have a system where we notify our users via e-mail when there has been a new login to their account. This system enables immediate detection of fraudulent logins by third parties. To learn more, please check the article below.

Cyberattack techniques are evolving by the day. We strongly encourage you to take protective measures yourself, such as deleting your password and setting up two-factor authentication or a passkey.
