Some resources require a specific username and password or link.
The Library Access browser extension will tell you that you need identifiers when you arrive on a site of this type.
Please do not divulge them beyond the University circle, it would be to your detriment:
- on the one hand, an abnormal activity would lead to a cut in access on the part of the publisher concerned,
- on the other hand, the number of simultaneous accesses is limited for some of these resources.
