Prestashop Checkout Update from v2.21.0 on Prestashop 1.6.1.x

[El_panda]

Hi,

We use the latest version of Prestashop Checkout (v2.21.0) before the new authentication system.

Since v6.3.1.0, it seems that the ps_accounts module is now needed in order to use Prestashop Checkout module.

- Is it necessary to be connected in ps_accounts module to install and use latest Checkout module version (v.6.3.5.0) ? Or ps_accounts just need to be installed (even without Addons account configured/connected) ?
- Our actual Checkout account is not the same as our Addon Accounts, is it a problem ?

Thanks,
