Encryption credentials have expired
this is very disturbing. Suddenly after the os upgrade, this stopped working and tried many thing. Yet no luck
What encryption credentials? Is it for your Filevault? Is it for a website?
Is on an older browser? Safari is only up to date on encryption on Ventura, Monterey, and Big Sur.
An alternate web browser is necessary for encrypted websites on older operating systems.
