user login for different Q&A websites

Question

if i have two websites how to allow user to login to both websites, if he/she has registered to only one website but idont want to share any other data only user registration related data.

Answer 1

You may set that. All Q2A sites that need to share same users must use the same database. Set different QA_MYSQL_TABLE_PREFIX for each site so all sites use different tables to store data.

Then set QA_MYSQL_USERS_PREFIX for all sites to be the same.

Beware! If you are reconfiguring already existing sites then you have to manually rename all tables and also references to tables in constraints. Check https://www.question2answer.org/qa/93861/foreign-constraint-error-on-submitting-ask-page
