I will probably get some backlash for this but... Why not take this as a learning opportunity and teach your wife how to be secure in her own personal accounts, using SuperGenPass and LastPass? She'll learn about how to make her own accounts secure, and will go on with that knowledge if she were to create any further more sensitive accounts for financial institutions etc. She is safer and more secure using the internet, now and hopefully in the future, and then you just give her the master passwords for SuperGenPass/LastPass, and there you go! Problem solved?
