We recommend using a password manager to generate and store a secure password.
In order to use pixiv more securely, please use a password that you are not using for other sites and that a third party won't be able to guess.
In your password you can use alphanumeric characters and symbols ( =+*:;!|$&%#@~.,?_"&#'(){}[]<>^/\ ).
Example of a strong password: Ffpq2Zh)zQBT
Please make sure to never share your password with others.
Follow the procedure from the following URL to change your password.

If the password you entered is easy for a third party to guess, an error message will appear asking you to change it to something more secure.
Please note that a password alone is not enough to fully protect your account against unauthorized access.
Refer to the article below to learn how to make your account even more secure.
