Shockingly, the word mono-use is (literally) unfindable in Google.

In Italian it’s monouso, do I need to explain its meaning? Isn’t it self-explanatory? You use it one time

But someone has caught on and given the name mono-use in their patent for a hypodermic syringe

Mono-use syringe for hypodermic injections

The invention relates to syringes suited for hypodermic injections and
more particularly to mono-use syringes for hypodermic injections.

The use of mono-use «throw-away» syringes is known. Typically,
«throw-away» syringes are packaged singularly in hermetically sealed
wrappers. This simple type of packaging is practical and guarantees
sterility of the syringe up until the moment that the syringe is used.

A problem associated with «throw-away» syringes is the possibility of
reuse of the syringe for further injections. Because there is no
assurance of hygienic conditions, repeated use of «throw-away»
syringes increases risk of transmission of various types of diseases.
The problems associated with the repeated use of «throw-away» syringes
has been well documented in the case of intravenous drug abusers who
commonly use syringes previously used by others.

The use of mono-use syringes having various mechanisms to render the
syringe inoperable after a single use is also known.

You could extend the use of mono and tag it onto almost anything e.g. «mono-user account» for those who wish to open a temporary account which would expire after a limited period. And «mono-use link» could be shortened to mono-link which is easier to pronounce than «single-use link». It could catch on.
