ive wondered the same thing.

i too created like 5 different npubs (not cuz i wanted to) when i was checkin out snort, primal, coracle, etc and messin with alby, like 3 different browser extensions, nwc, multiple ln wallets, etc. jeez, crazy.

anyway, ive more or less settled now on muun wallet, no browser extension, coracle ui and a little bitta snort with alby ext in a diff browser.
