I am interested in lending my passive holdings for generating income ( hopefully risk is minimal). I see two brokerages offers it  . I am not asking any recommendation on brokerages, but asking for personal experience of members who might have taken part( still taking or quit), pros and cons of it.

I am interested in lending my passive holdings for generating more income. Hopefully the risk is minimal. I see, for instance, two brokerages offering it. I am not asking any recommendation on brokerages, but about the pros and cons of this type of program. What should I be aware of when considering participation in such a program?
