devise Invalid Email or password - ruby-on-rails

Question

After adding styling to the devise pages, the logins are not working.
Signup redirects to login and login says Invalid Email or password.
Here is the sessions/new
<%= form_for(resource, as: resource_name, url: session_path(resource_name)) do |f| %>
<%= devise_error_messages! %>
<div class="access_social">
<%- if devise_mapping.omniauthable? %>
<%- resource_class.omniauth_providers.each do |provider| %>
<%= link_to "Sign in with #{OmniAuth::Utils.camelize(provider)}", omniauth_authorize_path(resource_name, provider), class: "button button--facebook button--full-width" %>
<% end -%>
<% end -%>
</div>
<div class="oauth__divider"><span>OR</span></div>
<div class="form-group">
<%= f.label :email %>
<br />
<%= f.email_field :email, autofocus: true, autocomplete: "email", class: "form-control" %>
</div>
<div class="form-group">
<%= f.label :password %>
<br />
<%= f.password_field :password, autocomplete: "off", class: "form-control" %>
</div>
<div class="clearfix mb-2">
<div class="form-check">
<%= f.check_box :remember_me,class: "form-check-input", as: :boolean if devise_mapping.rememberable? %>
<label class="form-check-label">Remember me</label>
</div>
</div>
<div class="actions">
<%= f.submit "Sign in", class: "button button--primary button--full-width" %>
</div>
<div class="text-center mt-2">
<%- if devise_mapping.recoverable? && controller_name != 'passwords' && controller_name != 'registrations' %>
<%= link_to "Forgot your password?", new_password_path(resource_name) %>
<br />
<% end -%>
</div>
<% end %>
Controllers routes and config have not been touched since changing the UI either
