Notes
This support information does not include support for other `autocomplete` values.
As described in detail below, many modern browsers ignore the `off` value on certain fields in certain cases intentionally in order to give the user more control over autofilling fields. One example is the use of password managers.
- Partial support refers to ignoring the `off` value for password fields. see related blog post
↑
- Partial support in Chrome refers to the browser intentionally ignoring `autocomplete="off"` when the user uses the browser's autofill functionality. see bug
↑
- Partial support in Firefox refers to ignoring `autocomplete="off"` for login forms. see bug
↑
- Browser does not display previously submitted values as options with `on` value.
↑
- Safari ignores the `off` value for username, email and password fields
