The simple answer to your quest is "No". The faucet has to be fasten on the
bottom using a nut that screws on the threads of the part of the faucet that
extends below the sink top. Perhaps the nut is on, but not tightened. It's
possible that it was hand tightened only (it should be wrench tightened) and
just got loose which allowed the faucet to move (it probably wasn't the
plumbers' putty that was holding it). Check with you hand to see if its
there and if you can hand tighten it. Then go out and get a basic wrench
That is "basin", not "basic" wrench. This funny wrench that can reach into
difficult places like this just for tightening this nut. Usually sold in
the plumbing dept. of stores.
(under $5) make it more permanent. Just a little bit beyond hand tightening
should do it.

Overall, M & B is/are correct. The faucet is held on by a nut (maybe with
washers), not with any sort of glue.
