## The problem
Issue triggerdotdev/trigger.dev#186 (closed, 19 comments): Logging into a locally-run Trigger.dev via magic link fails in Safari. With no RESEND_API_KEY set, the magic link prints to the terminal, but opening it in Safari 16.4.1 bounces you back to the magic-link page instead of into the dashboard. Sending the link by real email did not reproduce it, which pointed at a cookie/session quirk with the terminal-printed link in Safari.
## What fixed it
Resolved by a product change, per maintainer matt-aitken: when running the platform locally, Trigger.dev no longer sends a magic link at all and just logs you in directly. If you hit the Safari redirect loop on an older local build, upgrade to a release with this change. On current versions there is no magic-link step in local dev, so the Safari cookie issue cannot occur.
