Hi Zuleika Pauneto,
Adding to what Erica Chalfin said, it looks like you did not select the "I am an RSA customer or partner" option when Video Link : 33974 and validate your customer status and, as such, you do not have full customer access to the website.
Because the RSA Charge presentations are only accessible to customers and partners with one or more active maintenance contracts associated with their accounts, this would be why you are seeing the "Unauthorized" message. (For additional details, refer to the article entitled 000035653 - Where can I find the RSA Charge presentations on RSA Link?)
To remedy this, you will need to 000035296 - How to re-register as a customer or partner on RSA Link which will grant you the appropriate access to the presentations, as well as to other restricted resources such as product downloads, the Case Management portal, etc.
If you experience issues with re-registering, please contact RSA Customer Support using the form here: https://community.rsa.com/contact
Thanks!
Jeff
