### Sample Prompts

#### Sign Up&#x20;

```
I want to use Firebase Auth API to handle account creation and login. 
This is the sample code from their API: curl 'https://identitytoolkit.googleapis.com/v1/accounts:signUp?key=[API_KEY]' \ -H 'Content-Type: application/json' \ --data-binary '{"email":"[user@example.com]","password":"[PASSWORD]","returnSecureToken":true}'
```

#### Sign In

```
Use Firebase's Auth API to handle user login
This is the sample code from their API: curl 'https://identitytoolkit.googleapis.com/v1/accounts:signInWithPassword?key=[API_KEY]'
-H 'Content-Type: application/json'
--data-binary '{"email":"[user@example.com]","password":"[PASSWORD]","returnSecureToken":true}'
```

#### Reset Password

```
Add a "forget password" that makes an api call. 
Here is the sample code: curl 'https://identitytoolkit.googleapis.com/v1/accounts:sendOobCode?key=[API_KEY]' \ -H 'Content-Type: application/json' \ --data-binary '{"requestType":"PASSWORD_RESET","email":"[user@example.com]"}'
```

#### Send Email Verification

```
When users create an account, send an email verification through an api call. 
The sample code is this: curl 'https://identitytoolkit.googleapis.com/v1/accounts:sendOobCode?key=[API_KEY]' \ -H 'Content-Type: application/json' \ --data-binary '{"requestType":"VERIFY_EMAIL","idToken":"[FIREBASE_ID_TOKEN]"}'
```

#### Confirm Email Verification

```
When trying to login, check to make sure that the email is verified before letting them login. 
Sample code here: curl 'https://identitytoolkit.googleapis.com/v1/accounts:update?key=[API_KEY]' \ -H 'Content-Type: application/json' --data-binary '{"oobCode":"[VERIFICATION_CODE]"}'
```
