OAuth
Abbreviation for Open Authorization
In short and in plain language
OAuth is an open set of rules for how programs reach protected data.
The program does not need to know the user's password. Instead it gets a key that only works for a short time.
A shop may be linked to other programs. The rules say which system may read or change which data.
Definition
OAuth is an open standard that lets an application access protected data without knowing the user's password. Instead of credentials, it issues time-limited access keys called tokens. In shop and ERP integrations, OAuth controls which system may read or change which data.
