The two charges followed a lengthy garda investigation into the alleged circulation on the internet of images and details purported to involve the teenage killers of the 14-year-old schoolgirl.
Rebecca Ryan (25) appeared before Waterford District Court.
Ms Ryan, of Priory Lawn, Ballybeg, Waterford, faces two charges relating to the publication or circulation on social media in June 2019 of images of teenage boys in relation to Ms Kriegel's murder.
The social media platform involved was Twitter.
Under the terms of both an order by the Central Criminal Court trial judge involved and the Children's Act, nothing relating to the identity of the two teenage boys charged with Ana's murder could be published or circulated.
The woman did not appear in person in court before Judge Kevin Staunton in accordance with strict Covid-19 control regulations.
Following consultations, Judge Staunton accepted jurisdiction in the case meaning it can be dealt with before Waterford District Court.
The Director of Public Prosecutions (DPP) had indicated the matter could be dealt with summarily before the district court.
Judge Staunton confirmed the appointment of solicitor Hilary Delahunty to act for Ms Ryan and adjourned the proceedings until December 10.
At that date, the court will hear details of a plea and when a date for hearing can be set.
Judge Staunton was told that garda statements in relation to the matter have been handed over to the defence legal team by Det Garda Niall Carolan of the Garda Detection HQ section at Harcourt Square following a request for all materials.
Dublin teenager Ana Kriegel was subjected to a brutal sexual assault in an abandoned house in Lucan on May 14, 2018 and was then murdered.
Following a trial last year, two teenage boys - who were 13 years old at the time of the killing - were convicted of her murder. They were the youngest offenders to be charged with murder in the State.
By strict order of Mr Justice Paul McDermott and under the terms of the Children's Act, neither can be identified until they are 18 years old.
Boy A was sentenced to life in prison with a review period after 12 years for her murder.
He was also sentenced to 12 years for aggravated sexual assault.
Boy B was sentenced to 15 years for Ana's murder with the sentence to be reviewed after eight years.
Both are serving their sentences at the Oberstown Centre.
A major garda investigation was launched when images and details were circulated online.
