Hi Ernest,
Have you considered using badges? You can use the free version of what was called Badgr, now called "Canvas Credentials." You can build in badges to be issued automatically upon completion of certain requirements in the Canvas course, and these badges can be digitally authenticated. You can enter what assessments were required to earn it as well as objectives. These badges can then be added to LinkedIn, Portfolium/Canvas Student Portfolios, etc. You can even add expiration dates for your badges for learners to recertify after a certain period of time.
With the paid version, you can even make Learning Pathways for stackable credentials. Would you like more information on this?
