remember password between sessions

[Pierre Abbat <phma@webjockey.net>]

I'm translating the wikipedia interface, and here's one of the difficult 
phrases. I currently have:
"rememberpassword" => "morji le sivyvla entre sessões",
Two questions:
1. What is the word for "session"?
2. The word for "between" (bi'i) is a conjunction, not a preposition. I could 
say "ca lo -session bi'i lo -session", but is there a better way?
