Hi and thank you for your question.
Typically homemade mayonnaise is considered unsafe. The concern is with the raw (unpasteurized egg). I'd be hesitant to give any homemade mayo with pasteurized eggs to young children, older adults, pregnant people, and the immunocompromised, due to weakened immune systems.
In general regardless of the mayo, you would want to keep leftovers in your fridge for 3-4 days at a temperature in your refrigerator of 40 degrees Fahrenheit or lower.
