Dear Blessed,
As others have said, you need to have your wife choose the password. Furthermore, the e-mail address given to K9 (where the password will be sent should it be lost) must be one that you have no access to - preferably your wife's.
As to why you need this protection, there are several reasons you can give. First, as noted by others, countless Rabbanim have said that there is an Issur Yichud for men to be alone with an unfiltered computer. These Rabbanim aren't only speaking to us - they wouldn't trust themselves either (otherwise, the comparison to an Issur Yichud would be imprecise). So, you can tell your wife that you're not better than Rav Matisyahu Solomon (e.g.). Second, you want to set a good example for the children.
Hatzlacha!
Dear Kedusha,
I am not aware of
countless rabbonim who hold that there is an actual issur of yichud. (However, that does not diminish the problem.) If you are,
please let me know who they may be. Thanks.
Regarding adding issurim, please see what the Chaye Odom brings down about potatoes. I don't have it in front of me, but he brings down, on the bottom, from a seifer, "Boruch Hashem that there were no potatoes (ed. at least known) in the times of Chazal, because they then would have assured them as kitniyos".
To me it's mashma that even though they
would have, since they
did not[i], there is no problem - as far as kitniyos goes.
Again, it cannot be stressed enough that there are other reasons to treat the internet
as if indeed it was a problem with yichud --- and then some!
- rather we share what worked for us ;D
