A public petition against plans to shelve the pensions dashboard has climbed from 17,000 to more than 82,000 signatures since Thursday.
The petition, hosted by 38degrees, was launched six days ago.
Backlash against the government has emerged over the past week as rumours swirl that ministers are considering abandoning the planned 2019 introduction of the dashboard.
Adviser trade body Pimfa is also calling on the government to move forward on the plans.
The call comes after work and pensions secretary Esther McVey says the dashboard is distracting from the roll out of universal credit.
Pimfa senior policy adviser Simon Harrington says Pimfa is “extremely disappointed by speculation” of cutting the plans.
Calling on the government to stand by its commitment, Harrington says the dashboard will play a crucial role engaging savers and reducing the cost of advice.
LEBC Group director of public policy Kay Ingram says the introduction of the dashboard will also protect consumers from fraud.
She says: “A 21st century tech-led dashboard will be critical in achieving good retirement outcomes. We very much hope that the government will press ahead.”
