Hi @SumitBadrakiya; welcome to our Community and thanks for using our Transfer feature.
To directly cut to the chase, transfers are automatically set to expire after 7 days when on the free, Basic plan, but Professional, Business Advanced, Enterprise, and Education users have the option to add a password and set the transfer to expire in 7, 30, 60, or 90 days according to their needs.

I hope this clears things up and I'm always around if you have any more questions Sumit.
