I was testing my login/sign up feature and for some reason I can't understand Firebase now is blocking all requests from my device.
I've waited one day to try again, but I still have the same problem.
ERROR: "We have blocked all requests from this device due to unusual activity. Try again later."
What should I do to have access to my database again?
I contacted firebase support and received this message: The error "We have blocked all requests from this device due to unusual activity. Try again later." is usually thrown when a user is making SMS authentication requests to a certain number of times using the same phone number or IP address. These repeated requests are considered as a suspicious behavior which temporarily blocks the device or IP address. Additionally, there's a limit of 5 SMS per phone number per 4 hours. With this, you may try doing the following to resolve the issue: Reduce the frequency of attempts to avoid triggering the anti-abuse system Try using whitelisted phone numbers for testing your app Use multiple testing devices (as the limits are applied per IP or device) Wait for an hour for the quota to lift I tried to increase the quota as per @lhk answer but there answer is the following: You also mentioned that you have increased the quota to 1000 but it didn't work. Do note that this "Manage to sign up quota" field is intended for Email/Password and Anonymous sign-ups.
