Migrate from tokens to certificates
Complete these steps to migrate from Krajowy System e-Faktur (KSeF) tokens to certificates.
Understand the migration timeline:
-
Tokens and certificates are both supported KSeF authentication methods.Note:
Tokens were previously scheduled for deprecation on January 1, 2027. Poland's Ministry of Finance has reversed this decision and confirmed that tokens have no planned end date. Migration to certificates is optional.
-
Migrate to certificates if you need offline invoice issuance, batch transmission, or prefer certificate-based authentication.
-
Certificates are available for download from the KSeF portal starting November 1, 2025.
-
During the migration, it's recommended to run tests either in the Test ( https://ksef-test.mf.gov.pl/) or Demo ( https://ksef-demo.mf.gov.pl/) environments to validate your configuration before production deployment (https://ksef.podatki.gov.pl/).
-
Migrating from tokens to certificates follow the same process explained below for all the environments.
After completing these steps, your system uses certificate-based authentication for all KSeF submissions.
