Introduction to the auto-fill user name and password function in the Safari browser: With the help of "auto-fill", you can easily fill in the previously stored user name and password. You can also create a strong password when setting a password on the website. The fields where the information has been entered are highlighted in yellow.
Fill in username and password
In the Safari browser app on the Mac, do one of the following:
If you have previously stored your username and password for the website, please use "Autofill" to enter the information and log in. Click the username field, then choose your username (or use the touch bar). If your Mac is equipped with a touch ID, you can use the touch ID to fill in your stored username and password and log in. If the webpage has an option to remember your information (such as the "remember me" checkbox) and you want to use that option, please select it before using Touch ID. If your Mac is connected to an external display when the built-in display is turned off, enter the Mac account password and click "Autofill."
If the user name and password of the website have not been saved, please save the information so that you can use the "autofill" function next time. Enter a username and password, or automatically create a strong password (as described below), and then click "Use a strong password" when asked.
