Poland extends the use of tokens as an authentication method indefinitely.

Tokens were expected to remain a valid KSeF authentication method only until December 31, 2026. In response to requests from businesses and software providers, the Ministry of Finance has decided to extend their use indefinitely. 

The change is reflected in the KSeF Manual 2.0, Part I, but will take legal effect only once the amended Regulation on the use of KSeF is published.
