okay so here's snapchat app so if you tap on your account and then um tap on your icon uh tap log out and here you will have the option to remove account so here is the account okay if i just tap on it it will automatically lock me back in but to remove that account just tap on that button under the profile picture and then you'll be the account will be removed from snapchat from this profile so it means that if you then need to login to your accounts on this mobile phone you need to enter a username and password but if you have this account saved here you can just yeah login with one tab you can also use another account and yeah just add another account so that's how it works
