Yours to tune

Turn on what you like. OttoKey can fill codes automatically, open itself when one is on the way, and even tidy the email into Trash after reading it — but only after you say yes.

  • Auto-fill straight into the page
  • Pops open the moment a code lands
  • Always grabs the newest code on a resend
  • Inbox tidy-up, off by default (recoverable for 30 days)
