As of midnight this morning, the FBI gained authority to hack into computers, networks, and phones with simple blanket federal warrants, as explained this morning in a typical story in New York magazine here.
The Senate did not stop this authority. Previously, multiple local warrants would have been necessary.
It’s not likely that this could affect most users (“if you aren’t doing something you shouldn’t be doing”). It’s unclear if major computer security firewall products will prevent the hacking. The FBI may want this capability particularly to counter terrorism and recruitment by foreign enemies (ISIS) which Trump is likely to continue.
