Sign a document with your SL-UDI identity
A government service that signs a PDF with an identity verified by SL-UDI. You download the signed document, and anyone you share it with can check who signed it and confirm it has not been altered since.
What you need
The PDF, and your phone for the SL-UDI one-time code.
PDF only, up to 10 MB
One document per signing.
Tamper-evident
Any change to the document after signing breaks the signature, and verification will say so.
