There have been some mentions on here of some customers receiving excessive recaptcha messages in the recent past. I have just tried logging in, in quick succession, to 5 different VM email accounts (which has been a trigger for recaptcha to appear for me in the past) but no security prompts were triggered. Other past suggestions for the prompts have included things like fast typing/entry of credentials and/or other unusual activity from the customer's network as being a cause for the recaptcha trigger.
Have you considered gradually migrating your email requirements/usage over to a third-party provider outside of any ISP? If you were driven to moving your broadband/TV to another provider and away from VM, your VM email account(s) would close within 90 days of your service ending and you would lose access. With a third-party email provider, you can move broadband providers without affecting your email usage. You might also get better security such as 2FA depending which alternative service you chose.
