How do I remove "powered by Shopify" from the footer?

You can remove the "Powered by Shopify" link from your footer by editing your theme code, finding the Sections folder, opening footer.liquid, and deleting this line, around line 73.

<p class="footer__small-text">{{ powered_by_link }}</p>

Starting Expanse 5.0.0, Fetch 2.0.0, and Gem 2.0.0, the "Powered by Shopify" link can be found in the section-footer.liquid in the Snippets folder of the theme. Look for the following code and delete it from the file:

{{ powered_by_link }}

As for the Password Page, the "This shop will be powered by Shopify" can be removed in the layout/password.liquid. Simply delete this code:

{{ 'general.password_page.powered_by_shopify_html' | t: shopify: shopify }}

For Expanse, Gem, and Fetch you'll be looking for this line of code:

{{ 'info.will_be_powered_by_html' | t: shopify: shopify }}
