Installing font from Glyphs Mini into iFont on iPad gives "not signed" notice

I have completed my first font and installed it on my iPad using iFont. After installing it on iFont, I am directed to go to the iPad settings for the Profile Downloaded area. In the Install Profile there’s an area “Signed by” followed by “Not Signed” in red letters. I noticed this happens on other fonts and not just mine. Is there something I should do to prevent this “not signed” notice from showing and can it be done in Glyphs Mini? I have filled out all of the Font Info I can in Glyphs. The “not signed” notice doesn’t prevent me from installing the font but if I ever wanted to sell a font, would that be a problem?

Thanks for any suggestions. I did not see any discussion on the forum about this but if there has been maybe someone could kindly direct me to the place it was discussed.

Fonts are usually not signed.
But resource put on iOS need to code signed. This has nothing to do with the fonts, it applies to everything like apps, too. You might need to check with iFont to resolve this.

Thanks Georg for the speedy reply. I’ll try contacting iFont.
