Palpatine is not Anakin's father in either Canon or Legends. In Legends, Plagueis and Palpatine tried to manipulate the force for their own desires but the Force didn't like that and so it retaliated and created Anakin, the Chosen One.
Anakin Skywalker is the son of Shmi Skywalker, born without a father through the Force. He is the secret husband of Padmé Amidala, the father of Luke Skywalker and Leia Organa, the father-in-law of Han Solo, and the maternal grandfather of Ben Solo.
In an early Revenge of the Sith draft, Palpatine confirmed that Darth Plagueis used the Midi-chlorians to start the cell division that created Anakin Skywalker.
With his mother stating he has no father, it's often been theorized that either Dark Plagueis or the future Emperor Palpatine were responsible for Anakin's conception via the Force. One Darth Vader comic from 2019 did seemingly reveal that Palpatine was responsible.
Darth Sidious was the secret persona of Sheev Palpatine and the Sith apprentice of Darth Plagueis. The time period of when Plagueis came to possess his Sith apprentice was unknown, but the Dark Lord chose Sheev Palpatine, a human from Naboo, as his apprentice.
Because as soon as Kylo defeated Snoke, Darth Plagueis infected him. He is no longer Kylo Ren, he is now assumed by Darth Plagueis, and it is Darth Plague's desire to rule.

In The Phantom Menace, when Qui-Gon Jinn meets tiny Anakin Skywalker and his mother, he goes on about how the Force is like, crazy strong with Anakin or whatever, and then asks his mother about Anakin's dad. Shmi Skywalker is pretty clear in her answer: There isn't a father. She was impregnated by the Force.
At the end of Star Wars: Episode II - Attack of the Clones, Anakin and Padme are secretly married.
In The Rise of Skywalker (2019), the final film in the sequel trilogy, Palpatine is revealed to be the mastermind behind the First Order and creator of its puppet leader, Snoke, as well as the grandfather of protagonist Rey.
Star Wars Legends literature elaborates on Plagueis' life, apprenticeship under the Bith Sith Lord Darth Tenebrous, and mentorship of Palpatine, up until his death at the latter's hands.
1 Darth Sidious
There has been no Sith, as powerful, meticulous, nor as evil as the Emperor himself, Darth Sidious. As previously mentioned, Sidious trained in the Dark Side by Darth Plagueis before Sidious killed Plagueis in his sleep, making Sidious a Sith Master.
The Star Wars universe establishes Snoke as a Force-sensitive artificial being created by Emperor Palpatine to reclaim control of the galaxy. As Palpatine's puppet ruler, Snoke leads the First Order against the New Republic and manipulates Luke Skywalker's nephew, Ben Solo, into becoming Kylo Ren.
Midi-chlorian counts were linked to potential in the Force, ranging from normal Human levels of 2,500 per cell to the much higher levels of Jedi. The highest known midi-chlorian count—over 20,000 per cell—belonged to the Jedi Anakin Skywalker, who was believed to have been conceived by the midi-chlorians.
Star Wars reveals Emperor Palpatine learned Luke Skywalker is Darth Vader's son during The Empire Strikes Back. After Anakin Skywalker turned to the dark side and became Vader, his children were hidden to keep them save from the clutches of the Emperor.
Reva knows that Anakin Skywalker is Darth Vader because she was one of his targets—a child—during the Order 66 killings that took place during the events of Star Wars Episode III: Revenge of the Sith.
Senator Padmé Amidala of the planet Naboo became pregnant during the Clone Wars with her husband, Jedi Knight Anakin Skywalker, as the father. She gave birth to twins, Luke Skywalker and Leia Organa.
She does not have a baby bump, her hand never goes to her stomach to indicate she's carrying a child, and there wasn't exactly any time for her to have conceived a child with anyone in the course of the film, including Kylo Ren/Ben Solo.
Han Solo marries Princess Leia and they have three children: twins named Jacen and Jaina, and a younger son named Anakin. Luke reestablishes the Jedi Order, marries a non-movie (but fan favorite) redheaded Force-wielder named Mara Jade, and they have a son, Ben Skywalker (named in honor of Obi-Wan “Ben” Kenobi).
However, Leia's strong-mindedness during Vader's probe denied him the opportunity to discover she was his daughter. That serves to justify Vader's lack of awareness of his connection to Leia, although, perhaps, not as satisfyingly as if Lucas had planned for the relationship from the beginning.
Despite being enemies, Rey and Kylo Ren share a connection called a 'Force dyad' and eventually become romantically involved with one another. Following Palpatine's final defeat and her own resurrection, Rey adopts the name Rey Skywalker to honor her mentors and their family legacy and renounce her lineage.
At the end of Star Wars: The Rise of Skywalker, Rey visited Luke's childhood home on Tatooine. While on the planet, when someone asked her who she was, Rey responded by saying that she was "Rey Skywalker." Although she wasn't related to them, both Luke and Leia had been mentors to Rey throughout the sequel trilogy.
If not, the only logical explanation is that Jar-Jar is a member of the Sith. There are many theories surrounding the enigma that is Jar-Jar Binks. The most agreed upon theory, started by Reddit user Lumparoo in 2016, is that Jar-Jar is a powerful Force-user conspiring with Darth Sidious.
Palpatine killed Plagueis because his usefulness was at an end. Similarly, Palpatine viewed his future apprentices the same way he'd come to see his master. They were all tools to be discarded when they had served their purposes in his greater plans.
According to Star Wars Legends content, the first Sith was a former Jedi Master, Ajunta Pall, who became a so-called Dark Jedi, or “Fallen” Jedi. As the name implies, these Force-sensitives chose to practice the Dark Side, and rejected the Light Side of the Force.
