Why does there's a captcha when I'm only using my mobile phone to login here in the forum while there's no captcha when I login using desktop browser. I just notice it now when I browse using my company desktop for the first time.
To be very honest, i never encounter such a thing, as every time when i login to my account i have to click on the button saying that "i am not a bot" and sometimes it automatically "approves" without filling or giving any imaging test and few times it asks me to give image test. Well, i do have to click on it whether i am at the phone or a laptop.
Sometimes the captcha on mobile keeps giving me a result to try again even I'm sure that I'm choosing the right tile. Do you encounter this too on the mobile version? It's just annoying sometimes to captcha over and over on mobile because of the small screen.
Well, i also never faced such issue as I often log out of my accounts as i kept them logged in all the time. I think your device must have been tagged with some robotic script or something like that which has made google captcha think that you are a bot. Well, whenever I use VPN for anything on Google (not for BTT) they ask me to fill the captcha and start a captcha loop on me, even after many tries they never let me go forward so what i do is, turn off the VPN and then connect to another server and try again and after giving a first try to captcha, i get approval as human and i can do whatever i want. IDK, what type of work you do on your smartphone which might have tagged you as suspicious one in Google's eye. but still i am no expert in these scenarios I recommend you to read this out too.
This reCAPTCHA test takes into account the movement of the user's cursor as it approaches the checkbox. Even the most direct motion by a human has some amount of randomness on the microscopic level: tiny unconscious movements that bots can't easily mimic. If the cursor's movement contains some of this unpredictability, then the test decides that the user is probably legitimate. The reCAPTCHA also may assess the cookies stored by the browser on a user device and the device's history in order to tell if the user is likely to be a bot.
