Dear NikoNN
Thank you for using Microsoft products and posting in the community.
The problem of being reminded of too many requests when logging into your account may be caused by an anomaly in your current network environment when connecting to the Microsoft server, you can try the following:
1 Enable a VPN or proxy and migrate from your current network environment to another country or region. Or, if you have enabled a VPN or proxy, you will need to disable the VPN or proxy and change your current network environment to your home environment.
2 Restart your home router. This is because restarting the router will reset the network.
3 Log in with a different browser
4 Log in using your browser's privacy mode
