How to find an old PF account after changing jobs?

Changing jobs leads to multiple Provident Fund (PF) member IDs, but the money is still present in those accounts. If a person loses their PF IDs, they can find their Universal Account Number (UAN), which remains consistent across jobs, using the EPFO member portal. Using the UAN, the EPFO passbook can be found, which contains details of old PF contributions.
