Where can I hardcode a translation of "Remember Me"?

[Foreigner]

Hi. Not a biggie… I realize that the “Remember Me” in the login is included in the new UP po file. However, for the moment I want to hardcode it as the translation file I need–Spanish–has a few syntactical errors and is written in the formal (WP, BBpress, etc are all written in the preferred informal). I neverthless certainly appreciate the hard work that must have gone into what is otherwise a fine translation. (I plan to translate and share a new Spanish version–at least for the frontend–but it’ll be some time before I am finished, as I am busier than usual this semester.)

In the meantime, can someone tell me in which file I can hardcode the “Remember Me” phrase? (I’ve found a couple of others I needed, but not this.)

Thanks!
