# Trouble Signing In or Receiving a Verification Code

This article covers common sign-in problems — missing verification codes, forgotten passwords, and trouble with Google sign-in — and how to fix them.

## How you can sign in

CordLine offers two ways to sign in:

- **Email and password** — CordLine sends a short verification code to your email during sign-up to confirm it's really you.
- **Google** — one-tap sign-in using your Google account, no password to remember.

If you use two-factor authentication or High Security mode, you'll also enter a code from an authenticator app or a text message as a second step. See our article on setting up two-factor authentication.

## A verification code isn't arriving

1. Check your spam or junk folder — verification emails sometimes land there.
2. Give it a minute; codes can take a little time to arrive.
3. Make sure you're checking the same email address you signed up with.
4. Request a new code if the first one doesn't show up.

## Trouble with your password

If you've forgotten your password, use the **Forgot password** link on the sign-in screen. You'll be sent a reset link by email.

## Trouble with Google sign-in

If "Continue with Google" isn't working:

- Make sure you're signed into the correct Google account on your device.
- Try signing in from a browser if the app version isn't working, or vice versa.
- If you originally signed up with email and password, use that instead — Google and email sign-in aren't interchangeable for the same account unless they're linked to the same email address.

## "This email is already in use"

If you see this when signing up, you likely already have an account. Use **Sign in** instead of **Sign up**, and try Forgot password if you can't remember your credentials.
