Imho, I'm not a fan of Jagex Accounts or how they don't tell you it's not reversible upfront as you start the process of making it. But I'm also not one of the ones who were unlucky and the Jagex Launcher broke the game and made it impossible for them to log in either. Or one of the ones who had a compromised email which gave someone else access to all their characters regardless of the extra security. Idk how it works for those using Mobile or Steam, but I've heard it mentioned that playing through Steam made Jagex Accounts easier.
If you added your other Runescape Accounts to your Jagex Account, you don't need to type them in. Just log into the Jagex Account using the Jagex Launcher, select the account you want to play ~ (Play) (Dropdown menu to select which character) (Manage Characters) ~ right above (News). Assuming you added them to your Jagex Account. If you did not, they won't be in that dropdown menu.
Also, if you make separate Jagex Accounts, just know that you will need to log into the Jagex Launcher > select char to play and start > Log out of the Jagex Launcher > Log in on your next Jagex Account > Check email or w/e to authenticate > Finish your login to launcher and choose character to play > Repeat over and over if you are multiboxing and set all your Runescape accounts as separate Jagex Accounts. You can only have a single Jagex Account logged in to a Jagex Launcher on a single device at a time. Even if you try installing it on separate drives of your computer.
One last thing, not only is it irreversible when you make a Jagex Account, but the same when you add your Runescape characters to it. So be sure to think hard about the "extra security" before you add a character to a Jagex Account permanently. As long as they aren't tied to a Jagex Account, you can use the old launcher easy peasy.
