Genesis mining doesn't let you sign up with a password longer than 16 characters

That is the smaller of the problems with Genesis Mining... This kind of investiment just give profit to the site owner and for the Ads networks. Who buys the Mining Power just lose money hoping to have some passive income profit. Hard to believe that there is people investing on this kind of Cloud Mining these days. Many other people lost lots of money with it. Some time ago I believed those sites, but never more!
I have seen so many people promoting Genesis Mining but after the closure of HashOcean I do find shared mining companies to be doubtful. Honestly, I did take a look at Genesis especially since they have been in business for years and I assumed they are already stable. However, online opportunities can sometimes be shaky so we have to be careful...be very very careful.
