I just call them web3 authenticators, best word I can think of to describe authenticating. That can be Alby or Metamask or any other kind of signer. Also the perception of web3 representing shitcoins or blockchains (decentralised ledger technologies [insert unicorn poo]) is something I'd credit to the most recent years. Hardly anyone spoke about web3-anything before 2020 when it became popular through ETH and Metamask.
