Hi SamataValluri
Thank you for your question.
You can call our colleagues at the SBB Contact Center (0848 44 66 88, CHF 0.08/min) and give the customer numbers of your daughters, they will send you a new link.
If you want to upload the photos on SwissPass directly, you need to set up a personal SwissPass account for each of your kids.
I wish you a great day
Regards
EleonoraS
