If I purchase the Laser e-portfolio or already use the Laser e-portfolio and want to add Laser Learning resources, will my learners have two logins to separate platforms?

No.

The Laser e-portfolio incorporates the learning resources which are available separately on a Laser Lessons system. Laser Lessons is specifically for those who do not want to purchase the Laser e-portfolio or are already using a different e-portfolio. The advantage of using the Laser as your e-portfolio is that learners can access everything in one place.
