# --description--

With `type="password"` you can use the `pattern` attribute to define a regular expression that the password must match to be considered valid.

Add a `pattern` attribute to the password `input` element to require the input match: `[a-z0-5]{8,}`

The above is a regular expression which matches eight or more lowercase letters or the digits `0` to `5`. Then, remove the `minlength` attribute, and try it out.

# --hints--

You should give the password `input` element a `pattern` attribute.

```js
assert.isNotEmpty(document.querySelector('input[type="password"]')?.pattern);
```

You should give the `pattern` attribute a value of `[a-z0-5]{8,}`.

```js
assert.equal(document.querySelector('input[type="password"]')?.pattern, '[a-z0-5]{8,}');
```

You should remove the `minlength` attribute from the password `input` element.

```js
assert.equal(document.querySelector('input[type="password"]')?.minLength, -1);
```
