In a similar vein, make sure that things like your fingerprints aren't easily shown in any photos you share online. Take this almost hilarious example from a couple years ago as to why you should be careful about including your fingerprints in photos you upload.
A drug dealer was identified because of a picture of a block of cheese he posted online, and was subsequently arrested. In the photo, it clearly showed his fingerprints thanks to modern camera technology allowing for higher image resolutions.
If law enforcement is able to capture a person's fingerprint reliably through a photo, then so can anyone else. With enough time and skill, a bad actor use it for nefarious purposes and potentially even unlock your phone with a rubber mold.
Remember, you can always change a password, but you can't change your fingerprint.
