JWTlogin allows WordPress to use a remote user authentication system based on JWT (Json Web Token) and one time cryptographic key. 
Through this plugin it will be possible to connect our WordPress installation to a GDPR (General Data Protection Regulation) compliant authentication system and with a security level at the bank level, in the basic and military version in the advanced version. 
The system is compatible with any other access customization plugin and also allows for authentication of user documents (ID and proof of residence), required by current international legislation. 
User data is fully encrypted and inaccessible except to the owner or manager of data management. 
The plugin is completed by the possibility of creating a personalized frontend, through development kits or templates, of the pages received from the site https://auth.ssolo.co.uk.
