# --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);
```
