When you forgot your password for the Magento customer account and try to reset your password, Many times you can see the error message like,
“We received too many requests for password resets. Please wait and try again later or contact email@example.com.”
This is a Magento native feature to allow only 5 times per hour to reset the password.
If you want to get rid of this limit you can change the native value to 0 from the Admin panel.
Go To Admin Panel Navigation menu,
Stores -> Configuration -> Customers -> Customer Configuration -> Password Options

The default value is 5.
Click on Top right Save Config Button.
Using Set 0(Zero) value, You can reset any no. of times Password reset and Error will be not thrown again.
