Only one IPv6 link local unicast address is possible per interface?

[ekc]

Hi, members!

1. I met the following sentence. Is it true or false ?

    " Only one IPv6 link local unicast address is possible per interface "

2. Can some Cisco devices have the secondary IPv6 link local address on an interface ?

I already read the articles like as

2. No
