wpAuth by Orcnd

what it does

this generates a secure login link for users it also creates user if it doesn't exist yet

but why ?

welp i needed a cross site login for wordpress. this plugin allows my other platform can login wordpress without register and login again

but how ?

first of all i wanted to do this in secure as possible

so it has stages

create a control key we need this key to create access key. we need this because we want to make this access key work only for short time of period so we create a control key has with time, email and master key
ask for access key with control key now we have control key we are able to ask for access key. plugin will provide an access key which will be only accessible for short time
now we able to request link for login with access key plugin will return an unique id which will expire in short time
redirect to user wordpress usr with unique id that page will make user login to wordpress
auto login page of wordpress will redirect user to page that specified in settings

here is a sequence diagram about it

how to use it

wordpress side

create a wordpress page and add shortcode [wpAuth]
set settings on wordpress settings general section you need to set key, full redirect url, username prefix and some salt

api request side

## parameters that you will need

key: you need to store it wordpress plugin settings and your requester server
email : login user email
time : in ISO 8601 date format

you need a control key generator function first on your requester server md5('key'.'email'.'time'.'control_key')

than make a rest request to your wordpress site method is post request parameters are email,time and control_token that you generated above endpoint for this request is /wp-json/wpauth/v1/token you will get an access token with this request as access_token

now we can request a link id with our access token in order to do that you need to make a request method is post request parameter will be email,name and access_token endpoint for this request is /wp-json/wpauth/v1/generateLogin

this request will return an unique id as login

now redirect the user to wordpress page that you created and added [wpAuth] shortcode before with get parameter ?token=login that login provided with last request
