It is!
The transposition cipher works by lining up the plaintext in 4 columns, with a minimum of 2 rows. Then you use X to complete the incomplete rows. The Vigenere password is supposed to be:
vige
nere
= vniegree
I misspelt vigenere as vignere while encrypting it, so the password is
vign
ereX
= veirgenX
I'm sorry about this, X should have double-checked his passwords. Thanks for pointing this out. Please do let me know if there are other issues
