Remembering passwords in browsers. What attribute is used in the algorithm?

Question

Google Chrome

By what attribute does the browser understand that this input refers to a login/email? name? id?
We need a cross-browser solution so that any browser can save a login-password pair.

Answer 1

If I'm not mistaken, then the browser will remember as the username (it can be email) the value of the input, which is located before the first input in the password form.

Answer 2

Atrubut of namecourse.
This is essentially a generally accepted standard for naming the fields "login", "email", "password", etc.
