If you have FileMaker 9 or 10, yes. FileMaker doesn't natively do a "Sync". You can simulate a sync, if you are careful about and understand how it works.
If you are just pushing data to, let's say, a web server a simple import would work.
One more thing, be very cautious about storing passwords in straight text fields. It is not a secure way to handle passwords. It's better if you are encrypting the data, but you still need to have a good understanding of what is going on. If you have that, then great...just stay away from storing passwords in plain text fields.
