Created account with a temporary email and don’t have a password. Can’t change email now.

I created my Reddit account using a temporary email address a while ago. At the time, I don’t remember setting a password (I may have signed up quickly and stayed logged in on my phone).

Now I want to update my email to a permanent one, but Reddit requires my password to change it. The problem is:

• I don’t know the password

• The temporary email is no longer accessible

Is there any way to add a new email or set a password without access to the original email?

I’d really like to keep this account if possible. Any advice would be appreciated.
