Although the app was put in place on October 1, the Scottish Government delayed enforcement of the scheme until Monday, October 18. This allowed businesses to prepare for the the full enforcement.
Ms Sturgeon has chosen to divert away from the app used by England and Wales – using software designed specifically for Scotland.
The vaccine passport app had been offered – but Scotland elected to develop its own.
The Scottish Government said it was told it would “take at least 12 months to get access to the NHS log-in” required for the NHS app, saying England and Wales share more infrastructure.
Users of the Scottish app have reported glitches since its release.
Issues faced by the vaccine passport app have prompted anger.
Murdo Fraser, Scottish Conservative Shadow Cabinet Secretary for COVID Recovery, is among those who have been critical of the app and the difficulties once it is fully enforced.
Mr Fraser told Express.co.uk: “The SNP’s vaccine passport scheme is their latest disaster in a long line of failures.
“At every turn, Nicola Sturgeon and Humza Yousaf have shown their arrogance and failed to listen to the massive concerns from businesses. Their Green allies also sold out their principled opposition to vaccine passports for an increase in their salary and Ministerial positions.

“If this botched SNP scheme isn’t scrapped, how chaotic will it be when it fully comes into force next week?”
However, a Scottish Government spokesperson denied these claims. They said: “These claims are not true. The SFA has confirmed any delayed entry into Hampden at the weekend had nothing to do with the certification scheme.”
But Mr Fraser believes that the vaccine passport app should be immediately dropped following issues the hospitality sector has faced.
Mr Fraser added: “Businesses had no choice but to ignore the SNP’s regulations as the app simply wasn’t working. They left them to try and implement this shambolic policy on their own over the weekend, due to the increasingly confusing messaging coming from the SNP Government.
“The SNP should have scrapped this policy weeks ago, but still the SNP Government refuse to admit they’ve got this wrong and admit their scheme has turned into a total embarrassment.
“The Scottish Conservatives will continue to push for these plans to be dropped immediately before struggling Scottish businesses suffer even more.”
Nicola Sturgeon has since apologised to the people of Scotland following the release of the vaccine passport app.
Ms Sturgeon said that the information needed “wasn’t being sent quickly enough from the NHS system to the app”.
After admitting it caused her “extreme frustration”, Ms Sturgeon said: “I apologise for that.”
The Scottish Government and the Scottish Football Association have been contacted for comment on this matter.
