How to prevent Chrome from changing font when autofilling username/password?

Here is working solution that worked for me in 2021 to prevent Chrome from changing font on password/username input fields:

input#username {
  font-family: "Rubik";
  font-weight: bold;
  color: blue;
}

input:-webkit-autofill::first-line {
      color: red;
      font-family: "Rubik"; 
      font-weight: bold;
}

<link href="https://fonts.googleapis.com/css?family=Rubik&display=swap" rel="stylesheet">
<input id="username" name="username"></input>

Also I noticed that for some reason display: flex conflicts with that code, take a look:

input#username {
  font-family: "Rubik";
  color: blue;
  font-weight: bold;
  display: flex;
}

input:-webkit-autofill::first-line {
      color: red;
      font-family: "Rubik";
      font-weight: bold;
}

<link href="https://fonts.googleapis.com/css?family=Rubik&display=swap" rel="stylesheet">
<input id="username"></input>

This seems to be a recent change in Chrome: Issue 953689: Previously entered form values overrides styling when moused over. As far as I’ve seen this happens both on macOS and Windows, anywhere autofill is presented to the end user. Apparently this has intentionally been done to fix a security issue with the previous implementation – Issue 916838: Security: Two autocomplete flaws together allow sites to invisibly read credit card numbers after a single keypress

There doesn’t seem to be a way to override those new styles at the moment – if the change in styles is really too obnoxious, you can either disable autofill (Disabling Chrome Autofill) or set your field’s font styles (font-family, font-weight, font-style, font-size to match that of Chrome’s autofill suggestions – as suggested here: https://stackoverflow.com/a/56997845/1798491)

try this!

      &:-webkit-autofill::first-line,
      &:-webkit-autofill,
      &:-webkit-autofill:hover,
      &:-webkit-autofill:focus,
      &:-webkit-autofill:active {
        font-family: Times, "Times New Roman", serif !important;
      }

you might only need this though

     &:-webkit-autofill::first-line

the others are just incase

How to change Chrome autocomplete styles on input:

input {
...
font-family: $body-font;
font-size: 1rem;
font-weight: bold;
color: #000;
background-color: #fff;
  
// Background color
&:-webkit-autofill {
  -webkit-box-shadow: 0 0 0 1000px #fff inset;
}
  
// Font styles
&:-webkit-autofill::first-line {
  font-family: $body-font;
  font-size: 1rem;
  font-weight: bold;
  // color: green;
}

}
