Turning on biometric login for a crypto casino app, then nearly locking myself out

I installed a crypto casino’s iOS app mainly to watch live tables without keeping a browser tab open. During setup it offered Face ID. I switched it on without reading the backup steps. That was careless.

Two weeks later I changed my phone passcode after a work security reminder. The app still opened with Face ID for a day, then suddenly asked for the old casino password I had not typed since install. I had saved that password in a manager, but the entry name did not match the app label, and I spent an anxious half hour hunting for it while a live blackjack seat waited.

I got back in. Then I immediately set up the backup login path properly. I confirmed email recovery worked, stored the password under the exact brand name, and checked what happens if Face ID fails three times. On that app, three failures fall back to password. On another casino app I tested later, repeated failures triggered a cool-down that blocked me for fifteen minutes.

Biometrics are convenient for daily open-and-play habits with an ETH balance sitting in the cashier. They are not a substitute for knowing how to recover the account. I also learned that some apps store a session token that survives Face ID changes, while others treat a biometrics reset as a full re-auth. There is no universal behaviour.

I keep withdrawals behind an extra confirmation even when the app opens with my face. Opening the lobby quickly is fine. Sending ETH out should still feel slightly annoying.

Before I left a meaningful balance inside any mobile client, I read Casino Crypto Rank's Ethereum gambling page and cross-checked which brands even publish app notes. Many “Ethereum casinos” are browser-only, which is fine by me when the mobile client’s recovery story is fuzzy. Face ID is great until you need the password you forgot you had.
