Morphology
The computing sense is a metaphorical extension of the concrete object 'key ring' that holds physical keys, so a learner who knows 'key' and 'ring' can plausibly infer a place that stores keys — here applied to digital keys. However, the specialized notion of a secure cryptographic repository and the technical implications are domain-specific and not fully predictable from the constituents alone, so the expression is only partially transparent.
Etymology
Key ring in computing borrows the picture of a metal ring holding keys: it is a safe place on your computer or phone that keeps digital 'keys' and 'passwords' together. So, the term now means 'a secure store for login details and keys'.
