There is no bypass for that verification step. To change the backup email, access to an existing verification method is normally required.
Use one of these supported paths:
- On the verification screen, select Show more verification methods if available and use another method that still works.
- If none of the listed methods are accessible, select I don't have any of these. That starts the account recovery or security info replacement process.
- After identity is verified, add a new sign-in or verification method:
- Go to the Microsoft account Security tab.
- Select Manage how I sign in.
- Select Add a new way to sign in or verify.
- If a security info replacement is started, a 30-day waiting period can apply before the new security info is usable. This waiting period cannot be bypassed.
If the account is prompting to send a code to another Microsoft email account such as Outlook.com, Hotmail, Live, or MSN, use two private browsing windows so both accounts stay signed in at the same time:
- Open the first account in a private/InPrivate window.
- When prompted for the code, leave that window open.
- Open a second private/InPrivate window.
- Sign in to the alternate email account there and get the code.
- Return to the first window and enter the code.
If the old backup email is no longer accessible at all, the supported route is recovery/security info replacement, not a direct change around the code prompt.
