Hi there! It sounds like when you try to log in to MyChart, you receive a security code (likely for two-factor authentication), but after entering that code, it logs you out instead of letting you in. I want to help get this sorted out for you.

To start, a couple of quick questions to understand better:
- Are you using the MyChart app or accessing MyChart in your web browser on Windows 10 with WebKit?
- When you get the code, are you entering it promptly (codes usually expire in about 10 minutes)?
- Do you close or navigate away from the MyChart tab or app while entering the code?

Sometimes, if the MyChart tab or app is closed or switched away from while entering the code, it will log you out automatically as a security measure. Also, sometimes cookies or cache issues in the browser can cause this behavior.

Here are a few steps we can try to fix this:

1. Stay on the same tab/window: Make sure you do not close or move away from the MyChart login tab/window while entering the code you received.

2. Clear browser cache and cookies: Since you are using a WebKit-based browser on Windows 10, clearing cache and cookies may help.
- Go to your browser settings.
- Find Privacy or History options.
- Clear browsing data – select cache and cookies, then clear.

3. Verify system time and date: Ensure that your device's clock and time zone settings are correct. Authentication codes depend on accurate time.

4. Try logging in via a different browser: For example, use Chrome, Edge, or Firefox to see if the issue persists.

5. Disable browser extensions: Sometimes ad blockers or privacy extensions interfere with login processes, so try disabling those temporarily.

6. Update the MyChart app or browser: Make sure you have the latest app version or browser updates installed.

If after trying these you still get logged out after entering the code, it may be a backend server or account-specific issue.

In that case, I recommend contacting MyChart support directly via email at [email protected] or through their support desk as they can check your account for lockouts or technical flags.

Please try these steps and let me know what happens. I’m here to help you get back into your MyChart account smoothly. Are you satisfied with this plan so far?
