How Do i get my BF gmail full access without touching his Phone?

Hey I heard people can hack Gmail id with one link. they just send the link through email and if he click on it then i can get the access of his Gmail id. is it really working? I'm just excited to know about it.
I wanna check my BF Gmail id.

Anyone here can help me or guide me about it?

waiting for the response.

you sound innocently evil

FYI I don't know to "hack" but something I write In this might be true but do your own research.
the thing you are looking for Is either a 1 click exploit or a 0 click exploit
both exploits are kinda the same but only one (1 click exploit) need for the person to Click something like a link, and a 0 click exploit just need to be sendt to him and its done

you could also do an old kinda way to get in but it takes time, its something of a script.
1. brute force "hacking" get his email address and a password list from google or anywhere, and then use a program to guess/go down the list off passwords.
2. social engineering. now this one is hard because you are not really hacking, and dont know how to explain this one.
3 you could get a program like a key logger and get him to log in on your pc. <- the most simplest one out of all of them

ps hope that he don't have 2FA, cause if he does, then its going to be harder than touching his phone
- hope i was to a little help

Replying here in case someone does post a guide for this, I might need it too
