# Integrating Authentication

{% hint style="warning" %}
**Note:** Authentication is not strictly necessary to build a working Roots implementation. If you are trying to get a minimal implementation of your store up and running, you can leave it out for now, and do it later.
{% endhint %}

## Why Authenticate?

There are a number of good reasons to have your users login. First of all, if a user is logged in, they will not need to re-enter all of their information every time they make a purchase, which will lead to a smoother experience and fewer cart abandonments. Additionally, some payment methods require users to have an account. If you offer discounts to particular user groups (e.g. seniors or veterans), users will need an account to be able to take advantage of them.

Finally, you are able to personalize the shopping experience for them. If they have made previous purchases, you can prioritize potentially relevant products in your menu, and in the future we will make it easier to do this.
