Hi AntiCompositeNumber, that did the job. I was not aware about https://www.mediawiki.org/wiki/Manual:Pywikibot/BotPasswords and following instructions given over there helped me log in. Thank you Pamputt

It does appear that BotPasswords are enabled on Lingua Libre (https://lingualibre.org/wiki/Special:BotPasswords), so I'd suggest trying that. For more information see https://www.mediawiki.org/wiki/Manual:Pywikibot/BotPasswords.
